Toru takes his dog to be groomed. The fee to groom the dog is $75 plus 6.75% tax. Is $80 enough to pay for the service? Explain.

Respuesta :

For this we need to work out what 6.75% of 75 is:

6.75% = 27/400

27/400 * 75 = 2025/400 = 405/80 = 81/16

81/16 = $5.06

If you add this to the $75 you get an answer of $80.06 which is 6¢

After taxes, the service would cost a total of $80.06 which means that $80 is not enough to pay for the service.

The cost of grooming the dog is $75 before taxes.

After taxes, the total cost is:

= Cost before tax + (1 x Tax rate)

= 75 + ( 1 x 6.75%)

= 75 x 1.0675

= $80.06

The amount is slightly higher than $80 so we can conclude that $80 will not be enough to pay for the service.
