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

Answer:
<em>Peter now has 54 baseball cards</em>
Step-by-step explanation:
<u>Percentages</u>
Assume Peter had x baseball cards in his collection. The 35% of his initial collection is 
35 * x / 100= 0.35x
We know that those 14 new baseball cards represent a 35% of his previous collection, therefore we can set a simple equation
0.35x=14
When we solve for x, we'll know how many baseball cards Peter had before
x=14 / 0.35 = 40
Peter had 40 cards, he added 14 new baseball cards, so he now has 40+14=54
Peter now has 54 baseball cards
