After |
1 p |
8 p |
Amount that Elyse had less than Marion
= 7 u - 4 u
= 3 u
3 u = 48
1 u = 48 ÷ 3 = 16
Amount that Elyse had at first
= 4 u
= 4 x 16
= $64
Amount that Marion had
= 7 u
= 7 x 16
= $112
The amount that Marion had at first and in the end remains the same.
7 u = 8 p
8 p = 112
1 p = 112 ÷ 8 = 14
Amount that Elyse had in the end
= 1 p
= $14
Amount that Elyse spent on the birthday present
= 64 - 14
= $50
Answer(s): $50
