Answer:
x = $20,000
the manufacturer's list price is $20,000
Explanation:
Let x represent the manufacturer's list price.
And c the amount she finally paid
Given that;
She received a discount of 18% off the manufacturer's list price
= x - 18%x
= x - 0.18x
= 0.82x
then had to pay 8% state sales tax.
C = (0.82x) + 8% of (0.82x)
C = 0.82x + 0.08(0.82x)
C = 0.82x + 0.0656x
C = 0.8856x
Since she paid $17,712
C = $17,712
C = $17,712 = 0.8856x
0.8856x = $17,712
x = $17,712/0.8856
x = $20,000
the manufacturer's list price is $20,000
