Henry had some stamps at first. After he bought another 68 stamps, he had five times as many stamps as before. How many stamps did Henry have at first?

Stamps |
Before |
1 u |
Change |
+ 68 |
After |
1 u + 68 = 5 u |
Number of stamps after he bought = 1 u + 68
Number of stamps that is five times as many stamps as before = 5 x 1 u = 5 u
5 u = 1 u + 68
5 u - 1 u = 68
4 u = 68
1 u = 68 ÷ 4 = 17
Number of stickers that Kim had at first
= 1 u
= 17
Answer(s): 17
