Ben had $8.50 less than Elijah. After Ben gave $1.90 to Elijah, Elijah would have four times as much money as Ben. How much money had Elijah at first?
| |
Elijah |
Ben |
| Before |
4 u - $1.90 |
1 u + $1.90 |
| Change |
+ $1.90 |
- $1.90 |
| After |
4 u |
1 u |
Ben had $8.50 less than Elijah. If another $8.50 was given to Ben, Elijah and Ben would have the same amount at first.
4 u - 1.90 = 1 u + 1.90 + 8.50
4 u - 1 u = 1.90 + 8.50 + 1.90
3 u = 12.30
1 u = 12.30 ÷ 3 = 4.10
Amount that Elijah had at first
= 4 u - 1.90
= 4 x 4.10 + 1.90
= 16.40 + 1.90
= $18.30
Answer(s): $18.30
