Question

The cost, in dollars, associated with fixing a computer is estimated by the expression 35x + 20y, where x is the number of hours required of a certified repairman and y is the number of hours required of a software specialist. Find the cost of a repair for which a certified repairman worked 5 hours and a software specialist worked 12 hours.​

Answer 1

475 dollars

Explanation:

let cost = c

35x + 25y = c

x = 5

y = 12

35(5) + 25(12) = c

175 + 300 = c

c = 475
