Answer 1

To find out how many minutes Pearl read this week, we can start with the information given:

1. Pearl read 50 minutes last week.
2. This week, she reads 75% more than that.

First, let's calculate 75% of 50:

\[ 75% \text{ of } 50 = 0.75 \times 50 = 37.5 \]

Now, we can find the total number of minutes Pearl read this week by adding this amount to the original 50 minutes:

\[ 50 + 37.5 = 87.5 \]

So, Pearl read 87.5 minutes this week.

Now, let's set up the equation as you requested:

Equation to show how to find 75% more than 50:

\[ 100% \text{ of } 50 + 75% \text{ of } 50 = ? \]

Substituting the values we calculated:

\[ 50 + 37.5 = 87.5 \]

Next, we can also express the equation using the distributive property. Instead of writing it as two separate percentages of 50, we can combine them:

\[ 100% \text{ of } 50 + 75% \text{ of } 50 = (100% + 75%) \text{ of } 50 = 175% \text{ of } 50 \]

So, rewritten using the distributive property, it becomes:

\[ (100% + 75%) \text{ of } 50 = 175% \text{ of } 50 \]

This means Pearl read 175% of 50, which gives us the same total of 87.5 minutes this week.
