Question

Sergio has 79 paintings in his art collection. He and other local painting collectors agreed to donate some paintings to the local museum. Each of the t collectors will donate the same number of paintings, and the total number of paintings donated by the collectors will be 48.
How many paintings will Sergio have in his art collection after his donation?
Write your answer as an expression.

Answer 1

It was stated in the problem that there are t collectors. Therefore, there are (t + 1) collectors including Sergio. Since each collectors will donate the same number of paintings and their total number of donated paintings is 48, each should contribute 48/(t + 1) paintings. So, after the donation Sergio will be left with 79 – 48/(t + 1) paintings.
