x

9.25

9.5

Step-by-step explanation:

A percentage change is computed using the formula ...

  (amount of change)/(original amount) × 100% = (percentage change)

Putting in the numbers from the problem statement, we have ...

  $570/$6000 × 100% = 9.5%

Since the only addition to the final price is sales tax, the percentage change is the tax rate.

The tax rate is 9.5%.

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
