### Instruction:
Christine figures it would take a pint of paint to paint the front and back of 1 door in her house.  She has 8 doors to paint.  At the paint store, she can either buy 8 separate pints of paint for $8.00 a pint or a gallon of paint (which is the same as 8 pints) for a flat $55.00  How much money will she save if she buys the gallon of paint instead of 8 pints?

### Response:
 ถ้าเธอซื้อ 8 พินท์ เธอจะต้องจ่ายเงิน 8*8 = $<<8*8=64.00>>64.00
ถ้าเธอซื้อแกลลอน เธอจะต้องจ่ายเงิน 55*1 = <<55=55>>55.00
ถ้าเธอซื้อแกลลอน เธอจะประหยัดเงิน 64-55 = <<64-55=9.00>>9.00
