Answer:
C. $7.80
Step-by-step explanation:
We are asked to find the total price charged for goods that cost $7.50 and with a 4% sales tax.
The total price of goods would be $7.50 plus 4% of $7.50.
[tex]\text{The total price of goods}=\$7.50+\frac{4}{100}\times \$7.50[/tex]
[tex]\text{The total price of goods}=\$7.50+0.04\times \$7.50[/tex]
[tex]\text{The total price of goods}=\$7.50+\$0.30[/tex]
[tex]\text{The total price of goods}=\$7.80[/tex]
Therefore, the total price of goods would be $7.80.
