#1
4 for 5 would mean each single M&M is 1.25 (5/4)
9 for 25 would mean each single M&M is about 2.78 (25/9)
4 for 5 is the better deal

#2
10 for 35 is 3.50 each (35/10)
12 for 40 is about 3.34 each (40/12)

#3
85 divided by four is 21.25 meaning you'd spend about 22 cents each
the hardware store has a better deal seeing as 19 cents each is cheaper

#4
so 13 divided by 1.4 is about 9.3 so Raisin Bran has less sugar per ounce of cereal
