Answer:
Step-by-step explanation: 800/x=100/17
(800/x)*x=(100/17)*x - we multiply both sides of the equation by x
800=5.88235294118*x - we divide both sides of the equation by (5.88235294118) to get x
800/5.88235294118=x
136=x
x=136
83% of 800=664
Subtract the 15 from the 133
you get 118
divide 29.50 from the 118
you get 4
