Solution

Let's denote the number of biology textbooks sold as x.

According to the problem, the number of math textbooks sold was three times the number of biology textbooks sold. So, we can denote the number of math textbooks as 3x.

The problem states that the total number of textbooks sold (math and biology) was 292. So, we can set up the following equation:

x (biology textbooks) + 3x (math textbooks) = 292

Solving this equation will give us the number of each type of textbook sold.

Combine like terms:

4x = 292

Then, divide each side by 4 to solve for x:

x = 292 / 4 x = 73

So, 73 biology textbooks were sold.

To find the number of math textbooks sold, multiply the number of biology textbooks by 3:

3 * 73 = 219

So, 219 math textbooks and 73 biology textbooks were sold.
