Total value |
37 u + 3700 |
13 u |
50 u + 3700 |
24 u + 3700 |
Amount that the spectators donated
= 37 x (1 u + 100)
= 37 u + 3700
Amount that the performers donated
= 13 x 1 u
= 13 u
Total amount donated
= 37 u + 3700 + 13 u
= 50 u + 3700
50 u + 3700 = 5700
50 u = 5700 - 3700
50 u = 2000
1 u = 2000 ÷ 50 = 40
Amount of more money donated by the spectators than the performers
= (37 u + 3700) - 13 u
= 24 u + 3700
= (24 x 40) + 3700
= $4660
Answer(s): $4660
