Mr. scott counted 85 customers in his store the first day it was open, and 170 customers the second day. what was the percent of increase in customers? a. 10% b. 50% c. 85% d. 100%

D. 100%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the second day's number, 170, and the old number is the first day's number, 85.

percent change = (170 - 85)/(85) * 100%

percent change = 85/85 * 100%

percent change = 1 * 100%

percent change = 100%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 100%.

D. 100%

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
