Answer 1

Do you have an idea what the linear equation would look like?

Answer 2

no..

Answer 3

Ok well 30 $ per hour... How could you model that part if "x" is the number of hours?

Answer 4

30 * 8.5 ?

Answer 5

yes that part is good so far :). But there is also an extra $50 charge! so you just need to add that part

Answer 6

so $305 ?

Answer 7

yup :)

Answer 8

thanks! how about this one

Answer 9

1st step... determine how many gallons of gas did they buy?

1 gallon -> 1.35$
x gallon -> 23.50$

Answer 10

do i divide ?

Answer 11

yes

Answer 12

so $17.40 ?

Answer 13

well 17.40 gallons

Answer 14

(maybe round it to 17.41..)

Answer 15

sorry my computer restarted..

Answer 16

so how far did they travel ?

Answer 17

well you have 17.40 gallons, and there is 8 initially in the tank, so 25.4 gallons

Now, 1 gallons gives 27 miles , so:

1 gallon -->27 miles
25.4 gallons --> x miles

Answer 18

so divide 27 and 25.4 ?

Answer 19

no, in this case you need to multiply

You can always do this set-up:
\[ \frac{1}{25.4}=\frac{27}{x}\], when you cross multiply you get:
\(1x = 27(25.4)\\
x = 27(25.4)\)

Answer 20

685.8 miles ?

Answer 21

yes

Answer 22

okay thanks ! next problem..

Answer 23

1 gizmo requires 36$ of materials, and 20$ in labour.. so each gizmo costs 56$

Answer 24

Now there are 50 gizmos..

Answer 25

i dont get it ..

Answer 26

1 gizmo --> costs 56$ (from 36 and 20)
50 gizmos --> costs xx$ ??

Answer 27

2800 ?

Answer 28

yes

Answer 29

There's also the extra 6000$ cost now which is the rent

Answer 30

so is 2800 the answer?

Answer 31

(the problem is a bit vague in not specifying how many months of expenses they are interested in.. I'm assuming here just 1 month)

Answer 32

well the rent is also a cost to consider

Answer 33

you have to add it to the cost of the gizmos
