A jacket is reduced from $20 to $14. By what percentage was the price of the jacket reduced? ?
Responses
A 25%25%
B 20%20%
C 15%15%
D 30%
To find the percentage by which the price of the jacket was reduced, we can use the formula:
Percentage reduction = (Original price - Reduced price) / Original price * 100
In this case, the original price of the jacket is $20 and the reduced price is $14. Plugging these values into the formula, we get:
Percentage reduction = (20 - 14) / 20 * 100
Percentage reduction = 6 / 20 * 100
Percentage reduction = 0.3 * 100
Percentage reduction = 30%
Therefore, the correct answer is D) 30%.

To calculate the total number of hours Patrick spent in exercise classes last week and this week, we need to add the hours of the Monday and Friday classes together.
For last week:
Monday class: 3 hours
Friday class: 1 hour
Total hours: 3 + 1 = 4 hours
For this week:
Monday class: 3 hours
Friday class: 1 hour
Total hours: 3 + 1 = 4 hours
To find the total hours for both weeks, we add the totals together:
4 hours + 4 hours = 8 hours
Therefore, the correct answer is C) 8 hours.

To find the total number of miles Marissa walked, we need to add the distance from school to the ice cream shop and the distance from the ice cream shop to her house.
Distance from school to the ice cream shop: 11 miles
Distance from the ice cream shop to her house: 2/3 of a mile
To add the distances together, we need to find a common denominator for the fractions. In this case, the lowest common denominator is 3.
Converting the fraction 2/3 to have a denominator of 3, we get: (2/3) * (3/3) = 6/9
Adding the distances together:
11 miles + 6/9 miles = 99/9 miles + 6/9 miles = 105/9 miles
Simplifying the fraction, we get:
105/9 miles = 11 6/9 miles
Therefore, the correct answer is B) 11 6/9 miles.
