Answer: She would require 16 ml cover 240cm^2 of her skin
Step-by-step explanation:
Let m represent the milliliters of sunscreen required to cover her skin.
Let a represent the area of her skin that was covered. She assumes the the relationship between milliliters of sunscreen and the area is proportional. Introducing the constant of variation, k, the expression becomes
m = ka
She uses 3 ml to cover 45cm^2 of her skin. Therefore,
3 = k × 45
k = 3/45 = 1/15
The expression becomes
m = a/15
The milliliters of sunscreen that Kelsey needs to cover 240cm to the power of 2 of her skin would be
m = 240/15
m = 16 ml
