Dwight company sells a kitchen set for $320 to promote July 4th, Dewitt ran the following advertisment: beginning each hour up to 4 hours we will mark down the kitchen set at 8% at the end of each hour we will mark up the set 3% assume in Gregg Swanson buys the set 1 hour and 30 minutes into the sale what will Ingrid pay? ​

A) 55

B) 52

Step-by-step explanation:

For a= number of apples , we can choose b=10-a bananas , then the number of cranberries is fixed depending on the number of a and b

then:

Number of combinations = sum of 10-a +1= 11 -a from a=0 to 10 = 11*10 - 10*11/2 = = 55

B) If there should be at least 2 types of fruit then

Combinations = Total number - combinations with 1 fruit = 55 - 3 = 52
