Answer 1

Answer:

I'm going to give you a general notion to solve problems involving percentages and then you can particularize this method to solve your exercise. In fact, let X be a real number, then X% = X / 100. So if you need to calculate X% of a number Y, then you should calculate (X)(Y) / 100 and this gives precisely X% of Y. For example, if X= 15, then

X% = 15% = 15/100. Now 15% of 350

is (15)(350)/100 = 52.5
