We are asked to find the amount paid in sales tax after a purchase of items each priced at $47.75 and $28.39. First, we will add these two prices to get the overall price, like this:
[tex]\begin{gathered} \text{total = \$47.75+\$28.39} \\ \text{total}=76.14 \end{gathered}[/tex]We will now calculate the 8.5% of this amount, by multiplying it by 8.5/100, like this:
[tex]Tax=76.14(\frac{8.5}{100})[/tex]Solving this we get:
[tex]\text{Tax}=6.47[/tex]therefore, Jamal paid $6.47 in sales tax
