If granola costs $2.20 per pound, how much does 0.8 pound of granola cost?
alexgriva [62]

Answer:

$1.76

Step-by-step explanation:

when you multiply 2.20x 0.8 you get 1.76. at first I thought division was needed, but the answer to 2.20/0.8 is 2.75- which is more than the original cost. (sorry if this is confusing but) 0.8 pound is less than 1 pound, so the answer would need to be less than 2.20.
