Question

Santa ordered a CD that cost $11.25. The tax was 4%, & the shipping was 6%. Use a percent greater than 100 to find Santa's total bill.

Answer 1

We are given that a CD costs $11.25. If the tax was 4% and the shipping was 6%, then the cost plus tax is given by:

`C_{}=11.25*(4)/(100)+11.25*(6)/(100)+11.25`

Now, we can take 11.25 as a common factor:

`C=11.25((4)/(100)+(6)/(100)+1)`

Adding the fractions inside the parenthesis we get:

`C=11.25((110)/(100))`

Therefore, the total cost is determined as 110% of the original cost. Solving the operations we get:

`C=12.38`

Therefore, the total bill is $12.38
