Tom sells baseball cards at 10 for 35 cents. Is that a better deal than 12 for 40 cents?

For either one of the deals, just find what one card equals and times it by how many cards the other equation has.

e. g. 0.35 cents divide by 10 = 0.035. And now, you times it by 12 since the other deal is 12 cards for 40 cents.

0.035 x 12 = 0.48

So, 10 cards for 35 cents is not the better deal.

1 case

35c : 10 = 3,5c

2 case

40c : 12 = 3, (3) c

3, (3) c < 3,5c

First option is a better deal than second version.
