Answer:

The best buy is the 0.74 kg box

Step-by-step explanation:

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.

We find the unit price for 1 box

a) The 0.425 kg box was on sale for $3.59

= 1 kg = $3.25/0.425

= $7.6470588235

b) the 0.74 kg box was on sale for $4.88,

1 kg = $4.88/0.7$

= $6.5945945946

c) the 0.95 kg box was on sale for $7.29.

1 kg = $7.29/0.95

= $7.6736842105

Which box of cookies was the best buy?

The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.
