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.

Answer:
=594
Step-by-step explanation:
(81)(66)(1)
9
=594
3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53
4(3y-1)=20
12y-4=20
12y=24
y=0.5
