@Qwertty123 @TheSmartOne @inkyvoyd @pooja195 @SolomonZelman @freckles

Answer 3

Where is your work for #1 ?

Answer 4

oh i will type it down right now @TheSmartOne

Answer 5

12.50*0.075=0.9375

Answer 6

0.9375 is 0.94 rounded

Answer 7

then 12.50+0.94=13.44

Answer 8

@TheSmartOne I showed my work

Answer 9

good job :)

now do the same for #2

this time you just multiply 15% by 240 and then add whatever you get to 240

Answer 10

ohhh

Answer 11

so $240.00*0.15=36

Answer 12

an easier way would be:

(240 x 0.15) + 240

factor out 240

240 ( 0.15 + 1)

240 (1.15)

So if you just did 240*1.15 you would get the answer more quickly :P

Answer 13

that way only works if we are adding tax to it, or bringing the price up

if we were doing a discount then it would look like:

240 - (240 * 0.15)

240 (1 - 0.15)

240 * 0.85

Answer 14

ohhh, ok so 240*1.15=276

Answer 15

and your way was basically:

240 + 36 = 276

and you got the ame answer! :D

Answer 16

same*

Answer 17

and 240*0.85=204

Answer 18

cool!

Answer 19

Do I do the same thing for #3?

Answer 20

nope, #3 has to do with a discount so we would have to do the second example I posted which was about subtracting instead of adding

Answer 21

oh ok...

Answer 22

1,400 - 0.35 = 1399.65 ...like that?

Answer 23

oh wait

Answer 24

1,400 (1,400 * 0.35) like that?

Answer 25

nooooooo

Answer 26

oh, was i right the first time?

Answer 27

nope, read what I wrote above carefully

Answer 28

oh you said if we were doing a discount it would look like that.

Answer 29

On my question it says what is the discounted price of the tv?

Answer 30

Answer 31

Answer 33

I am confused for this one

Answer 34

1400 * 0.35 = ?

Answer 35

= 490

Answer 36

1400 - 490 = ?

Answer 37

= 910

Answer 38

oh, my answer is 910

Answer 39

exactly, and the faster way of doing this would have been

1 - 0.35 = 0.65

1400 * 0.65

To see how we got this, consider this:


1400 - (1400 * 3.5)

= 1400 ( 1 - 0.35)

= 1400* ( 0.65)

Answer 40

I THINK I understand

Answer 41

Answer 42

I will open a new board

Answer 43
