Answer:
$80.15
Step-by-step explanation:
We can make an equation to solve this problem, that helps a lot. If h represented hours, we could make the equation 15.53h+s=157.8
Now we know that he worked 5 hours, so we can multiply 15.53 by 5 to simplify the equation.
15.53*5=77.65
So now the equation is 77.65+s=157.8.
Now, we can subtract 77.65 from both sides.
So now, our final equation is s=80.15
It cost $80.15 to buy supplies.
Hope this helps!
