Need . my son is trying to figure it out

answer:

i think 2.75

step-by-step explanation:

this is simple, all you must do is understand the base rate of price per pound. if it is 2.50 per pound and you need 1/5 of a pound, then you would divide 2.50 by 1/5 to get 0.50, since 0.50 is 1/5 of 2.50, so your total answer is 3.00$!
