Answer:
$45.65 total
Step-by-step explanation:
To find the total multiply the sale price by 1 + tax rate.
Total = 20 x 1.05
Total = $21.00
0.78 is what you get when you convert 78% to a decimal. You will take the percent sign off and add a 0. In front of it.
It will be the same thing with any other two digit number. Let’s say it is 23% and you want to convert it to a decimal, your answer will be 0.23
Hope this helps!!
