Answer:
We are given that a store announced that their $500 appliances were on sale.
The price of the appliances after discount is $475.
We are required to find the percent discount on the appliances.
To find the percent discount, we have to use the below formula:





Therefore, the percent discount on the appliances is 5%
40% = 40/100 = 0.40
Find 40% of 20
20 * 0.40 = 8
Solution: 8 students traveled
4k-36 = 9k-44
add 36 to both sides:
4k =9k-8
subtract 9k from each side
-5k=-8
k = -8 / -5 = 8/5
You multiply the dividend and the quotient
