Cameron and Sam want to buy a Kindle. Cameron has $20 and plans on saving $4 per week.

Sam has $35 and wants to save $1 per
week.

When will they have saved the same amount of money?

5 weeks

Step-by-step explanation:

Let x represent the number of weeks they have been saving

Create an equation that sets Cameron and Sams' savings equal to each other, then solve for x

4x + 20 = x + 35

3x + 20 = 35

3x = 15

x = 5

So, they will have saved the same amount of money after 5 weeks

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
