Answer 1

i believe the correct answer here is 53

Explanation:

so if 1 cookie is 70 cents, then you determine how many cookies is $36.90

you use proportion and say(convert to cents)

70: 1

3690: more

and calculating using proportion, you get 52.714285714286 and when you round it off it's 53. to prove your answer you say 0.7 × 52.7 = 36.9

Answer 2

.70x + 14.50= 36.90 x=32

Explanation:

0.7x=36.9-14.5

0.7x=22.4

x=32
