Total value |
32 u + 3200 |
8 u |
40 u + 3200 |
24 u + 3200 |
Amount that the spectators donated
= 32 x (1 u + 100)
= 32 u + 3200
Amount that the performers donated
= 8 x 1 u
= 8 u
Total amount donated
= 32 u + 3200 + 8 u
= 40 u + 3200
40 u + 3200 = 4400
40 u = 4400 - 3200
40 u = 1200
1 u = 1200 ÷ 40 = 30
Amount of more money donated by the spectators than the performers
= (32 u + 3200) - 8 u
= 24 u + 3200
= (24 x 30) + 3200
= $3920
Answer(s): $3920
