0 cover slips- 2 per person
0 Pasteur pipet 4 per person
3 micro pipet 100-1000uL- should have 5 per lab
0 micropipette tips- 4 per person
0 small test tubes-2 per person

Answer 2

Hmmm I am sorry I am not in this grade

Answer 3

okie :(

Answer 4

first you have to figure out how many haemocytometers, cover slips, pasteur pipets, etc you will need for the four classes of 20 students each. Then subtract the materials that you have in the inventory. Then see if the items you can purchase individually or per 1000. According to this you will order and multiplying for the price you will be able to find the invoice cost. at the end you have to add the 13% of sales tax.

Answer 5

do you need more help?

Answer 6

yes I don't understand yet

Answer 7

for example start with the first item in the list
haematocytometers, you need 20 per lab, you have 4 classes you will need 80 haematocytometers in total. According to your inventory you have already 16 so you have to subtract 80-16 to know how many you need to buy. That is 64 haematocytometers you need to buy for a $125 each (64 x $125 = $8000) you will need $8000 for the haematocytometers only. Then follow with the second item in the list, cover slips

Answer 8

the coverslips you need 2 per person, you have 4 classes with 20 students a total of 80 persons, at 2 coverslides per person that makes a total of 160 coverslides, you dont have any in your inventory you need 160, but they come in boxes of 100, you will need to order 2 boxes at 75 dollars each that makes $150 dollars for 2 boxes of coverslides.

Answer 9

but theirs 0 cover slips

Answer 10

the Pasteur pipets you need 4 per student (4 x 80 = 320 pipets) you have 0 in your inventory, you need to order 320, but they come in boxes of 100 for $100 a box. That is you need to order 4 boxes of 100. That is $400 for 4 boxes of pasteur pipets added to your shopping list.

Answer 11

hmm

Answer 12

yes you have to buy coverslips because there is 0 in the inventory

Answer 13

does that also go for the micropipette tips and small test tubes

Answer 14

yes, you don't have any coverslips, pasteur pipets, micropipets tips and small tubes, so you don't have to subtract any from the total that you need

Answer 15

anyway you are missing some data to complete the problem. You dont have the price of the RBC, you will need 80mL and you dont know how many serological pipets you will need for student. Without this two information you can not calculate the total invoice.

Answer 16

the cost of my RBC is says ( assume each student will take 1.0mL of rbc- 60$/500mL

Answer 17

ok we need 80 ml so we have to order the 500ml for $60

Answer 18

I don't understand the 3 micro pipet

Answer 19

I got it to the point that u explained it but the rest I just don't get it and with the 13% as well :/

Answer 20

you need 5 micropipets for each class you are planning for 4 classes (5 x 4 = 20 micropipets) you already have 3 in your inventory so you only have to buy 17 more micropipets at $295 each. It is a total of $4998

Answer 21

and I buy the tips for the micro pipet and also for the small test tubes and then at the end I total my amount times that by 13% ?

Answer 22

after you get the total of money that you have to spent to buy all the materials that you need you calculate the 13% of that amount and add that value to the total.

for example:
your total is $8000, the 13% of $8000 is (8000x13/100=$1040) so you have to add $1040 + $8000= $9040 this is going to be your total bill

Answer 23

ok im going to work on the micro tips and test tubes and then I will add all my money together then I add the 13% correct I hate how this is worth so much marks anything to do with MATH I just don't get it :(

Answer 24

BUT I REALLY appreciate ur help so very much

Answer 25

make a list as if you were going to the supermarket to buy that things, and at the end you should have a list has the cashier in the super give to you

Answer 26

Answer 29

One was instructed to prepare diluent for a class of 20 students. in determining the total amount of diluent needed each student would typically require slightly more volume. Assume each student will take 10% additional volume.
1) calculate the amount of diluent needed for a class of 20 students

this is another question completely different from the previous one
