Agrocery store sells raisins for $3.50 per pound and sells almonds for $4 per pound. keith bought just enough raisins and almonds to make a 2-pound mixture that is 40 percent raisins. how much did he pay for the raisins?

$2.8

Explanation:

Data provide in the question:

Selling price of the raisins = $3.50 per pound

Weight of the mixture = 2 pounds

Percentage of raisins in the mixture = 40%

thus,

the weight of raisins present in the mixture

= Percentage of raisins × Total weight of the mixture

= 0.4 × 2

= 0.8 pounds

Therefore,

the amount paid for the raisins = weight of raisins in mixture × price of raisin

or

The amount paid for raisins = 0.8 × $3.50 = $2.8
