x = 0.625

Multiply by 100%

x = 0.625 * 100\%

x = 62.5\%

<em>Hence, option (a) is correct.</em>

$20 haircut with 10% and 7% tax
Anika [276]

20 * .10 = 2  <em>(2 = 10% of 20)</em>

20 + 2 = 22

20 x .07 = 1.4  <em>(1.4 = 7% of 20)</em>

20 + 1.4 = 21.4

The price of a 20$ haircut with a 10% tax would be $22.

The price of a 20$ haircut with a 7% tax would be $21.40.
