lidiya [134]

Answer:

The total of Charlie's be $7.

Step-by-step explanation:

Given:

Charlie and his friend Jay went to the fair. They were having a sale and the admission was 25% off.

The regular ticket price was $9.00.

And the tax is 6%.

Now, to find Charlie’s total.

So ,we deduct the 25% off first:

$\$9.00-25\%\ of\ \$9.00$

$=9-\frac{25}{100} \times 9$

$=9-\frac{225}{100}$

$=9-2.25$

$=\$6.75.$

Now, including tax :

$\$6.75+6\%\ of\ \$6.75$

$=6.75+\frac{6}{100} \times 6.75$

$=6.75+0.06\times 6.75$

$=6.75+0.405$

$=\$7.155.$

Approximately = $7.

Therefore, the total of Charlie's be $7.
