Jonathan is purchasing apples from the grocery store. The apples cost $1.29 $1.29 per pound and there is a $0.25 $0.25 charge to

purchase a bag.
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

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
