A store sells small notebooks for $8 and large notebooks for $10. If you buy 6 notebooks and spend $56, how many of each size notebook did you buy?

Step-by-step explanation:

S + L = 6 => L= 6-S

8S + 10L = 56

8S + 10(6-S) = 56

8S +60 -10S = 56

-2S = 56-60

-2S = -4

S = -4/-2

S = 2

=> S = small notebook = 2

L = large notebook = 6-2 = 4
