Answer:
$74.40 cents
Explanation:
Given the following question:
20% of 62
In order to find the answer, we use the formula to calculate percentage, then we add that answer onto the bill.

![(20*62)/(100) =20*62=1240/100=12.4](https://img.qammunity.org/2023/formulas/mathematics/high-school/qcfxopiq0nijeqlawkhixxbiw4znjey1m0.png)
![=12.4](https://img.qammunity.org/2023/formulas/mathematics/high-school/z0visepmqi21r2ee9wtsmpe71ri1cjw70y.png)
Now add:
![62+12.40=74.40](https://img.qammunity.org/2023/formulas/mathematics/high-school/mwuqv25ef81osbhub24sncqqvbal0qitwy.png)
![=74.40](https://img.qammunity.org/2023/formulas/mathematics/high-school/tztivb4a39vslqvfeckr8xfssc6sp77mdn.png)
Which means in total after a 20% tip the Smiley family paid "$74.40 cents" for their meal.
Hope this helps.
