A textbook store sold a combined total of 343 history and chemistry textbooks in a week. The number of chemistry textbooks sold
was 59 less than the number of history textbooks sold. How many textbooks of each type were sold?
1 answer:
Let the number of History books be x. Then:-
x + x - 59 = 343
2x = 402
x = 201
So there are 201 History books and (201 - 59) = 142 Chemistry books.
