Two mechanics worked on a car. The first mechanic charged $85 per hour, the second mechanic charged $90 per hour. The mechanic worked for a combined total of 25 hours, and together they charged a total of $2200. How lond did each mechanic work?
Let the number of hours of 1st mechanic=F Let the number of hours of 2nd mechanic=S
F + S = 25........................(1) 85F + 90S =2,200...... ....(2)
Now you have 2 simultaneous equations. Can you solve them?
