Tommy had
15 as much money as Anna at first. After Tommy received $162 and Anna received $94, both of them had the same amount of money. How much did Anna have at first?
|
Tommy |
Anna |
Before |
1 u |
5 u |
Change |
+ 162 |
+ 94 |
After |
1 u + 162 |
5 u + 94 |
The amount that Tommy and Anna had in the end is the same.
1 u + 162 = 5 u + 94
5 u - 1 u = 162 - 94 = 68
4 u = 68
1 u = 68 ÷ 4 = 17
Amount that Anna had at first
= 5 u
= 5 x 17
= $85
Answer(s): $85
