Tommy and Andy had a total of 225 cards at first. After Tommy bought 25 more cards and Andy gave away 14 cards, Tommy now has the same number of cards as Andy. How many cards did Tommy have at first?
|
Tommy |
Andy |
Total |
Before |
1 u - 25 |
1 u + 14 |
225 |
Change |
+ 25 |
- 14 |
|
After |
1 u |
1 u |
236 |
Total number of cards in the end
= 225 + 25 - 14
= 236
2 u = 236
1 u = 236 ÷ 2 = 118
Number of cards that Tommy had in the end
= 1 u
= 118
Number of cards that Tommy had at first
= 118 - 25
= 93
Answer(s): 93
