Question

A painter charges $15.48 per hour, plus an additional amount for the supplies. If he made $142.51 on a job where he worked 4 hours, how much did the supplies cost?

A. $35.63
B. $61.92
C. $90.59
D. $80.59

Answer 1

he charges 15.48 per hour
so in
hrs charge
1 1(15.48)
2 2(15.48)
3 3(15.48)
4 4(15.48) in 4 hours

and additional for supplies, say "s"

in a job, he made a total of 142.51
so \(\bf 4(15.48)+{\color{brown}{ s}}=142.51\) solve for \({\color{brown}{ s}}\)

Answer 2

Thanks!
