Step-by-step explanation:
15 Gallon of Gas costs $37.50
To determine the Unit Price, we divide the Total Cost by the number of gallons of gas bought.
Unit Price

Expand = 2⋅2⋅x+2⋅3−(2⋅x−2⋅2)
Simplify = 10+2⋅x
Answer:
Cost(c)= $32.02
Step-by-step explanation:
20/100 = .20 now, out of a whole, .80 is missing so:
.80 x 38 = 30.40.
Now, we divide 5.5/100 = 0.055.
After, we times that by 30.4 = 1.62.
Now we know we need to add 30.40 + 1.62.
So, we get: $32.02 OR 32 dollars and 2 cents.
