David bought 3.5 pounds of apples that sell for $1.28 per pound and 2.4 pounds of bananas that sell for $0.55 per pound. how much did david pay for his fruit per pound?

First, determine the total David paid:  ($1.28/lb)(3.5 lb) + ($0.55/lb)(2.4 lb) =

                                                                  $4.48               +    $1.32      =   $5.80

Next, determine the total # of pounds of fruit David bought:  3.5+2.4 lb = 5.9 lb.

Then the average David paid per pound for his fruit was

              $5.80

              = $0.98

                5.9 lb

David paid an average of $0.93 per pound of purchased fruit.

based on context clues you gave i'm assuming the answer would be c.
