In a group of 40 people, 32 are over 5 feet 7 inches in height, and the others are under 5 feet 7 inches. If one person is selected at random from this group, what is the probability the person's height will be under 5 feet 7 inches?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

what i would say the best answer is a. 40.5

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
