Liam had some cards at first. After he bought another 68 cards, he had five times as many cards as before. How many cards did Liam have at first?
| |
Cards |
| Before |
1 u |
| Change |
+ 68 |
| After |
1 u + 68 = 5 u |
Number of cards after he bought = 1 u + 68
Number of cards that is five times as many cards 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
