3 pairs of shoes=30 meaning each shoe is equals to 10
2 boys +1 pair of shoes=20 since 1 pair of shoes is 10 then 20-10=10 since there are 2 boys, then 10 divided by 2 equals 5. 1 boy =5
food+food+boy=13
since we know 1 boy =5 therefore 13-5=8. There are 2 foods so 8/2=4
on the last equation
1 shoe(5)+ 1 boy (5)=10 x1 food(4)=40
so my answer is 40. anyone else?
