Suppose f and g are continuous functions such that g(4) = 6 and lim x → 4 [3f(x) + f(x)g(x)] = 36. Find f(4) =

C. Blueberries are $0.80 per pound less expensive at the farmer’s market.

Step-by-step explanation:

At a grocery store, blueberries come in 8-ounce container for = $2.80

Price per ounce in grocery store = 2.80 ÷ 8 = $0.35

As we know 16 ounce = 1 pound

Price of 1 pound blueberries at grocery store =  0.35 × 16 = $5.60

At a farmer's market, blueberries costs for 14 ounces = $4.20

Price per ounce in farmer's market = 4.20 ÷ 14 = $0.30

Price for 1 pound blueberries at farmer's market = 16 × 0.30 = $4.80

Difference in the price between farmer's market and grocery store is

$5.60 -  $4.80 = $0.80

Blueberries are $0.80 per pound less expensive at the farmer's market.
