Total value |
38 u + 3800 |
12 u |
50 u + 3800 |
26 u + 3800 |
Amount that the spectators donated
= 38 x (1 u + 100)
= 38 u + 3800
Amount that the performers donated
= 12 x 1 u
= 12 u
Total amount donated
= 38 u + 3800 + 12 u
= 50 u + 3800
50 u + 3800 = 4200
50 u = 4200 - 3800
50 u = 400
1 u = 400 ÷ 50 = 8
Total amount donated
= 38 u + 3800 + 12 u
= 50 u + 3800
50 u + 3800 = 4200
50 u = 4200 - 3800
50 u = 400
1 u = 400 ÷ 50 = 8
Amount of less money donated by the performers than the spectators
= (38 u + 3800) - 12 u
= 26 u + 3800
= (26 x 8) + 3800
= $4008
Answer(s): $4008
