Answer: A

Step-by-step explanation: Canoe → 8h →X

                                            Rowboat → 5h → Y

Fabrication department has at most 107, which means it need to be <u>less</u> than 107 hours.

This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.

8X + 5Y < 107

Mary used Delicious (d) and Golden Delicious (g) apples to make homemade applesauce. Delicious apples are $0.75 each and Golden
alina1380 [7]

Answer:

Mary bought 9 Golden Delicious apples

Step-by-step explanation:

This can be solved by setting up a system of equations. Based on the information given, the equations would be set up as follows.

.75d+1.25g=21.00\\d+g=22

I prefer to solve using substitution, but elimination can be used as well

.75d+1.25g=21.00\\g=22-d

We can now plug in this g value to the first equation

.75d + 1.25 (22-d)=21.00\\.75d + 27.5-1.25d=21\\27.5-0.5d=21\\-.5d=-6.5\\d=13

This means mary bought 13 delicious apples. She bought 22 apples in total,  so the total number minus the amount of delicious apples will give us the amount of golden delicious apples.

22 - 13 = g

9 = g
