Question

In a shop, the number of jackets is 8 more than three times the number of coats. If there are a total of 56 jackets and coats, how many jackets are in the shop?

Answer 1

44

Explanation:

Let c = number of coats.

Let j = number of jackets.

c + j = 56

j = 3c + 8

Substitute.

c + 3c + 8 = 56

4c = 48

c = 12

c + j = 56

12 + j = 56

j = 44

Answer: 44
