Answer:
$0.75.
Step-by-step explanation:
We have been given that Janet's dinner costs $7.50. She wants to leave a 10% tip. We are asked to find the amount of tip.
The amount of tip will be equal to 10% of $7.50.
[tex]\text{The amount of tip}=\$7.50\times \frac{10}{100}[/tex]
[tex]\text{The amount of tip}=\frac{\$75}{100}[/tex]
[tex]\text{The amount of tip}=\$0.75[/tex]
Therefore, Janet should leave $0.75 extra for the tip.
