Example Question #1 : Rewrite An Expression: Ccss.Math.Content.7.Ee.A.2

Sarah is going to buy a new cell phone. The cell phone costs $\$175$ plus a $10\%$ sales tax. What is the total price that Sarah will pay for her new cell phone?

Possible Answers:

$\$196.25$

$\$225.50$

$\$200.00$

$\$190.50$

$\$192.50$

Correct answer:

$\$192.50$

Explanation:

We know that Sarah is going to pay $100\%$ of the $\$175$ cell phone because that is the total cost. Plus, she is going to pay $10\%$ of the $\$175$ because that is the sales tax.

First, we need to convert our percentages into decimals in order to multiply.

$100\%\rightarrow1.00$

$10\%\rightarrow0.10$

Next, we can write a numeric expression and solve:

$1.00(\$175)+0.10(\$175)=1.10(\$175)$

$\$175+\$17.50=\$192.50$
