At first a price was decreased by 12%, then it was discounted again by an additional 5%. What is the percent of the total discou
olga_2 [115]
Hello there! I can help you! So we are decreasing a price by 12% and then doing it again by 5%. We would pay 88% of the original price and then 95% of that sale price. To execute this better, let's make a real-world situation. Say that Mariana wants to buy a new pair of shoes that originally costed $100. The store has a tag for 12% off and then an additional 5% discount at the counter. How much would she pay for the shoes? What total discount does she get? Let's start by multiplying 100 by 88%. 100 * 88% (0.88) is 88. That's the first part. Now, we multiply that number by 95% to find the price at the counter. 88 * 95% (0.95) is 83.6. That's the price with both discounts. Mariana would pay $83.60 for the shoes, but what about the percent discount total? Let's subtract that price from 100 and see what we get. 100 - 83.6 is 16.4. Percents are parts of 100, so we don't need to do anymore simplifying. There. The total amount of discount is 16.4%.

Olenka [21]

Answer:

A

I think your question is lack of information:

After one hour, the hare had finished 2/3 of a 100-yard race. In that same time, the tortoise had finished 42 3/4 yards. How much farther had the hare run than the tortoise?

Step-by-step explanation:

In one hour:

  • The hare: 2/3 of 100-yard race = 200/3
  • The tortoise: 42 3/4 yards = 171/4

How much farther had the hare run than the tortoise =  200/3 - 171/4 ≈23 yards.
