Question

A 5 pound bag of potatoes costs $2.77 while the store also sells individual potatoes for $0.59 per pound to make enough mashed potatoes to feed everyone at thanksgiving dinner you will need 7 pounds of potatoes

Answer 1

That would cost 3.95US$

Why that is correct:
$2.77 + ( $0.59 x 2 ) = $3.95

$0.59 x 2 = $1.18

$2.77 + $1.18 = $3.95

That’s how I did it
