The smiley family had a $62.00 bill and service was great! The tip 20% what is the. Total they paid

Georgia [21]

Answer:

$74.40 cents

Step-by-step 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.

$\frac{p\times n}{100}$
$\frac{20\times62}{100} =20\times62=1240\div100=12.4$
$=12.4$

<u>Now add:</u>
$62+12.40=74.40$
$=74.40$

Which means in total after a 20% tip the Smiley family paid "$74.40 cents" for their meal.

Hope this helps.
