4 u |
1 u |
Oscar had $1.60 less than Rael. If another $1.60 was given to Oscar, Rael and Oscar would have the same amount at first.
4 u - 3.40 = 1 u + 3.40 + 1.60
4 u - 1 u = 3.40 + 1.60 + 3.40
3 u = 8.40
1 u = 8.40 ÷ 3 = 2.80
Amount that Rael had at first
= 4 u - 3.40
= 4 x 2.80 + 3.40
= 11.20 + 3.40
= $14.60
Answer(s): $14.60
