From the equation given, there'll be 50 premium car washes and 75 quick car washes.
- Let x = Number of quick car washes.
- Let y = Number of premium car washes.
The equation given is:
x + y = 125 ..... i
5x + 8y = 775 ..... ii
From equation i,
x = 125 - y .... iii
Since 5x + 8y = 775
5(125 - y) + 8y = 775
625 - 5y + 8y = 775
3y = 775 - 625
3y = 150
y = 150/3
y = 50.
Since x = 125 - y.
x = 125 - 50.
x = 75
