Answer:
S = 935 when t ≤ 7
S = (180t - 325) when t > 7
Step-by-step explanation:
John's weekly salary = $375 + commission on number of cars he sell
Commission for the first seven cars sold = $80 per car
Commission above 7 cars = $180 per car
If John sells t cars each week then commission earned by John
= 80×7 + 180(t - 7)
So the salary for week = 375 + commission
S = 375 + 560 + 180(t - 7)
S = 935 + 180(t - 7)
S = 935 when t ≤ 7
(180t - 325) when t > 7
