Asked by D4VD

A computer technician charges a flat base fee plus an hourly rate for all repairs. Last year, she used the formula y = 18 x + 22 to determine the cost in dollars, y, of a repair that required x hours of work. If she doubles her base fee this year, what equation should she use to determine the new cost of an x-hour repair?
y = 18 x + 44
y = 36 x + 22
y = 36 x + 44
2 y = 18 x + 22

y = 18x + 44

Explanation: the hourly rate (18) stays the same, the base fee doubles from 22 to 44, so y = 18x + 44.
