Exercise #1

The price of the movie ticket rose from 40 to 45 pesos By what percentage did the price increase?

Step-by-Step Solution

In order to answer the question we must first understand how much the ticket costs:

45-40=5

That is, the price of the ticket increased by 5$.

Now we need to determine what the percentage value of the 5 pesos increase is. In order to determine this we will divide the increase by the original price and multiply it by 100 to convert it into a percentage.

5/40 * 100

We start by converting the 100 into fraction form.

5/40 * 100/1

When there is a multiplication of fractions, we can multiply numerator by numerator and denominator by denominator.

5*100 / 40*1

500 / 40

Thus we simplify as follows:

50/4

Lastly we convert the fraction into its complete form.

50/4 = 12.5

Answer

12.5%
