Assuming Jonathan needs to buy a bag, which function, c (a), where a

is the weight of the apples in pounds, represents the cost of his purchase?

c (a) = 0.25+1.29

c (a) = 1.54a

c (a) = 1.29a+0.25

c (a) = 0.25a

Fernando Doyle · Answer 1

cost of apples is based on weight (lbs) so this is the rate, the bag is a flat fee.

y = mx + b ⇒ Cost = rate (lbs) + bag ⇒ C = 1.29 (a) + 0.25

Answer: #3: c (a) = 1.29a + 0.25
