Ken had $2.40 less than Neave. After Ken gave $3.20 to Neave, Neave would have thrice as much money as Ken. How much money had Neave at first?
| |
Neave |
Ken |
| Before |
3 u - $3.20 |
1 u + $3.20 |
| Change |
+ $3.20 |
- $3.20 |
| After |
3 u |
1 u |
Ken had $2.40 less than Neave. If another $2.40 was given to Ken, Neave and Ken would have the same amount at first.
3 u - 3.20 = 1 u + 3.20 + 2.40
3 u - 1 u = 3.20 + 2.40 + 3.20
2 u = 8.80
1 u = 8.80 ÷ 2 = 4.40
Amount that Neave had at first
= 3 u - 3.20
= 3 x 4.40 + 3.20
= 13.20 + 3.20
= $16.40
Answer(s): $16.40
