Answer:
The farmer's market apples cost $1.50 per pound.
The grocery store apples cost $1.35 per pound.
Samantha should buy her apples from the grocery store, where the apples cost $0.15 less per pound than the farmer's market apples.
Step-by-step explanation:
The graph shows that 2 pounds of apples costs $3.00, so divide the cost by 2 for the cost of a single pound:
3 ÷ 2 = 1.5
Solve for the grocery store apple cost per pound by replacing x with 1 in the given equation:
y = 1.35(1)
Then solve for y:
y = 1.35
