Braylon · Answer 1

First, determine the number of donuts that needs to be purchased for 8 people in the meeting by substituting 8 to the function, d (x).

d (8) = 3x + 2 = (3) (8) + 2 = 26

Use this value to be x in the function h (x).

h (26) = 2x + 7 = 2 (26) = 59

Therefore, the manager should shed out 59 to buy the donuts.
