A tool set is on sale for 424.15. The original price of the tool set was 499.00. What percent of the original price is the sale price? How do you solve this?

499-424.15=74.85

499:100=4.99

74.85:4.99=15 is the percent of the discount

100-15=85 is the percent of the original price that you pay

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
