Question

A textbook store sold a combined total of 312 history and psychology textbooks in a week. The number of psychology textbooks sold was 84 less than the number of history textbooks sold. How many textbooks of each type were sold?

Answer 1

Answer: History textbooks sold: 198

Psychology: 114

Step-by-step explanation: 312- 84= 228

228 divided by 2= 114

Add 84 to 114 to represent the history textbooks since they have more.
