15% of the toddlers in a preschool class drink water with their lunch. How many toddlers are in the class if 3 drink water with their lunch? (a) Write a proportion for the situation.
(b) Solve the problem. Show your work.

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

y - 25 = 2 ( x - 10 ) should be the answer
