Omar wants to purchase a bike helmet for 22.55 and a bike for 134.45.
noname [10]

Answer:

$169.96 dollars

Step-by-step explanation:

Given the following questions:

8.25% of 22.55 and 134.45

In order to find the answer, we will have to add the initial costs of the items together, then we will calculate using the formula for percentages to find the tax rate.

22.55+134.45=157
157

<u>Calculate the percentage:
</u>\frac{p\times c}{100}
\frac{8.25\times157}{100} =8.25\times157=1295.25\div100=12.9525
=12.9525
12.9525
2 < 5
=12.96

<u>Add the sales tax:</u>
157+12.96=169.96
=169.96

Which means the two items along with an 8.25% sales tax costs "$169.96 dollars."

Hope this helps.
