Step-by-step explanation:
To solve, multiply the cost before tax with tax, and then add the number gotten to the original amount.
12 x 7.5% = 12 x 0.075 = 0.9
12 + 0.9 = 12.9
$12.90 is your answer.

Since you have not presented any choices wherein we can determine the best answer, I will go on and share my thoughts on how she could improve the results of her survey.
Since she just surveyed her ballet class, she should opt for surveying on other classes with other genres. This would entail reliability and validity and eliminate bias about the results.
<em><u>Division equation is:</u></em>

There are 2816 calories in whole pizza
<em><u>Solution:</u></em>
Given that,
A 14- inch pepperoni pizza is sliced into 8 equal pieces
One slice contained 352 calories
Therefore,
1 slice = 352 calories
Let "c" be the calories
Given that there are 8 equal pieces
<em><u>Therefore, calories in 8 pieces are:</u></em>
Calories in 8 pieces = 8 x calories in 1 piece

Thus the division equation is:

Therefore,

Thus there are 2816 calories in whole pizza
