Total value |
35 u + 3500 |
15 u |
50 u + 3500 |
20 u + 3500 |
Amount that the spectators donated
= 35 x (1 u + 100)
= 35 u + 3500
Amount that the performers donated
= 15 x 1 u
= 15 u
Total amount donated
= 35 u + 3500 + 15 u
= 50 u + 3500
50 u + 3500 = 5400
50 u = 5400 - 3500
50 u = 1900
1 u = 1900 ÷ 50 = 38
Total amount donated
= 35 u + 3500 + 15 u
= 50 u + 3500
50 u + 3500 = 5400
50 u = 5400 - 3500
50 u = 1900
1 u = 1900 ÷ 50 = 38
Amount of less money donated by the performers than the spectators
= (35 u + 3500) - 15 u
= 20 u + 3500
= (20 x 38) + 3500
= $4260
Answer(s): $4260
