Question

Viktor plays piano and baseball every day. He plays baseball each day for 1.5 hours. He plays piano for p hours each day. After 5 days, he played piano and baseball for a total of 12 hours.

Answer 1

Answer: d. 5(p + 1.5) = 12

Explanation:

Viktor plays baseball for 1.5 hours per day. In 5 days therefore he would have played:

= 1.5 * 5 days

He also plays piano for p hours each day. In 5 days he would have played:

= 5 * p days of piano

If both of these combined is 12, the expression would be:

(1.5 * 5) + (5 * p) = 12

Factoring them using 5:

5 * (1.5 + p) = 12

5(1.5 + p) = 12
