A textbook store sold a combined total of 452 sociology and biology textbooks in a week. The number of sociology textbooks sold was three times the number of biology textbooks sold. How many textbooks of each type were sold?

Respuesta :

The Number of biology books is 113 and the number of sociology books is 339 books.

How to calculate the value?

Based on the information given, let the number of biology books = b

The number of sociology = 3 × b = 3b

Therefore, the equation will be illustrated as:

b + 3b = 452

4b = 452

Divide

b = 452/4

b = 113

Number of biology books = 113

Number of sociology books = 3 × b

= 3 × 113

= 339 books
