Total amount of money that Orlando earned at the weekend for washing windows is $92.25.
He worked 3.5 hours on Saturday and 6.75 hours on Sunday. Total number of hours worked during the weekend would be the sum of the number of hours worked on Saturday and the number of hours worked on Sunday. It becomes
6.75 + 3.5 = 10.25.
Since Orlando charges the same amount for every hour he works, the amount that he earns per hour would be 92.25/10.25 = 9
100%/x%=80/20
(100/x)*x=(80/20)*x - we multiply both sides of the equation by x
100=4*x - we divide both sides of the equation by (4) to get x
100/4=x
25=x
x=25
