Question

Sarah used to make $8 per hour babysitting. She now makes $10.50 per hour. What is her percent increase to the nearest percent?

A) 29%
B) 31%
C) 32%
D) 33%

Answer 1

Sarah's percent increase in her hourly babysitting wage from $8.00 to $10.50 is calculated as a 31.25% increase, which rounds to 31% to the nearest percent.

Step-by-step explanation:

To calculate Sarah's percent increase in her babysitting wage, you subtract her old wage from her new wage and then divide by her old wage. Finally, multiply by 100 to get the percentage.

Sarah's old wage was $8.00 per hour and her new wage is $10.50 per hour. The difference is $10.50 - $8.00 = $2.50. Now, divide the increase by her original wage: $2.50 / $8.00 = 0.3125. To get the percentage increase, multiply by 100: 0.3125 * 100 = 31.25%, which rounded to the nearest percent is 31%.

Therefore, the correct answer is B) 31%.
