Question

$15 represents 20% of the spending money Judy is saving for a camp this summer. What is the total amount of money she hopes to take to camp

Answer 1

lets say that she is saving x dollars
so
20% of x is 15

\(\large x \times \large \frac{20}{100}=15\)
\(\large x \times \frac{1}{5}=15\)

\(\large x=15 \times 5\)
\(x=75\)
