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.

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.
