1. maria and daniel

Explanation:

Step1: Determine Choice 1

Last year Jordan had 80 games, now he has 100. Since \( 100>80 \), the number of video games increased. So Choice 1 is B. Increased.

Step2: Calculate the percentage change for Choice 2

The formula for percentage increase is \( \text{Percentage Increase}=\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times 100\% \)
Old value \( = 80 \), New value \( = 100 \)
First, find the difference: \( 100 - 80=20 \)
Then, calculate the percentage: \( \frac{20}{80}\times 100\%=\frac{1}{4}\times 100\% = 25\% \)
So Choice 2 is C. 25%

Answer:

Choice 1: B. Increased
Choice 2: C. 25%
