Answer to Problem 8CYU

The number of hours of practice for $15$ and $22$ school days are $37.5$ and $55$ respectively.

Explanation of Solution

Given information:

Total practice $12.5$ hours for $5$ days in a week.

Calculation:

for $1$ day number of hours practice $=\frac{12.5}{5}$

for $15$ days number of hours practice $=15\times \frac{12.5}{5}=37.5$

for $22$ days number of hours $=22\times \frac{12.5}{5}=55$

Hence,

The number of hours of practice for $15$ and $22$ school days are $37.5$ and $55$ respectively.
