Question

PLEASE HELP As a part-time job, ethan makes deliveries for a caterer. In addition to his weekly salary, he is also paid 16$ Per delivery. Last week, he made 5 deliveries and his total salary was $215. Write a linear equation to find Ethan's total weekly salary S if he makes d deliveries.

Answer 1

you know he made 5 deliveries for $16 each.  5*16=80.  So to find his salary you have 215-80=$135.

So he makes $135 no matter what plus $16 times the number of deliveries.

so, S=16d+135
