Find the unit price and tell which is the better buy:
Buy one 10 pack of AAA batteries for $5.49 and get one free, or buy two 4 packs for $2.98.

I did the last problem for you. Now it's your turn.
I'll be glad to check your answer.

Could you please check my answer?
I did this:
10+10=20.
5.49/20=0.2745 per battery
4+4=8
2.98/8=0.3725 per battery
The better deal is if you buy the one 10 pack for $5.49 and get one free.
