x*45%=86*100
45x=8600 /:45 (divide both sides by 45)
x=191.11 - its the answer

Answer:
D, B
Step-by-step explanation:
Price per pound is found by dividing dollars by pounds.
Store A: $9/(3 lb) = $3.00 /lb
Store B: $9.75/(3 lb) = $3.25 /lb
Store C: $12.40/(4 lb) = $3.10 /lb
Store D: $14.50/(5 lb) = $2.90 /lb
<u>Part A</u>: The lowest price per pound is $2.90 per pound at store D.
<u>Part B</u>: The highest price per pound is $3.25 per pound at store B.
