Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 425 g box was on sale for $4, the 740 g box was on sale for $6, and the 950 g box was on sale for $8. Which box of cookies was the best buy?

740 g at $6 was the best buy

Step-by-step explanation:

Lets work out the price per gram,

1) 425g at $4 = 0.425/4 = 0.10625 g

2) 740g at $6 = 0.740/6 = 0.12333 g

3) 950g at $8 = 0.950/8 = 0.11875 g

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
