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:

$C_{}=11.25\times\frac{4}{100}+11.25\times\frac{6}{100}+11.25$

Now, we can take 11.25 as a common factor:

$C=11.25(\frac{4}{100}+\frac{6}{100}+1)$

Adding the fractions inside the parenthesis we get:

$C=11.25(\frac{110}{100})$

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
