Total value |
36 u + 3600 |
14 u |
50 u + 3600 |
22 u + 3600 |
Amount that the spectators donated
= 36 x (1 u + 100)
= 36 u + 3600
Amount that the performers donated
= 14 x 1 u
= 14 u
Total amount donated
= 36 u + 3600 + 14 u
= 50 u + 3600
50 u + 3600 = 4400
50 u = 4400 - 3600
50 u = 800
1 u = 800 ÷ 50 = 16
Total amount donated
= 36 u + 3600 + 14 u
= 50 u + 3600
50 u + 3600 = 4400
50 u = 4400 - 3600
50 u = 800
1 u = 800 ÷ 50 = 16
Amount of less money donated by the performers than the spectators
= (36 u + 3600) - 14 u
= 22 u + 3600
= (22 x 16) + 3600
= $3952
Answer(s): $3952
