Question

five daughter share a gift of $100. Each girl except the youngest gets $5 more than her next youngest sister. How much does the youngest girl get?

Answer 1

$10

Explanation:

Let x be the amount the youngest sister gets

x + (x+5) + (x+10) + (x+15) + (x+20) = 100

5x + 50 = 100

5x = 50

x = 10
