How much did he pay?

Question

Lucus bought a refrigerator .his total cost of $1,331 included sales tax at the rate of 8% and an additional,untaxed delivery charge of $35.how much sales tax did he pay 

Answer 1

Let x be the original price of the refrigerator. 

The tax is then .08x

delivery charge of 35

 

x + .08x + 35 = 1331

1.08 x + 35 = 1331 

1.08 x         = 1296

x                  = 1200

 

So the refrigerator was 1200

the tax was 96

delivery charge of 35 

 

These total to 1331, so they're right.

 

Answering the question, the tax was $96.

 

Hope this helped.
