so he has 7.00
if we assume that he wants to buy more than 1 bagle and 1 container of cream cheese, then read explanation A, if he wants to buy more than 1 bagle, but only 1 container of cream cheese, then read explanation B
AAAAAAAAAAAAAAAAAAA
b=# of bagles he can buy
c=# of containers of cream cheese he can buy
cost of bagles=# of bagles times cost per bagle=0.75 times b
cost of creem cheese=# of cream cheese contaners times cost per container=1.29 times c
so total cost=7.00 (if he wants to max it out)
7.00=0.75b+1.29c
BBBBBBBBBBBBBBBB
if he wants to buy only 1 container of cream cheese then we just find how much bagles he wants to buy
b=# of bagles bought
cost of bagles total=b times 0.75 or 0.75b
total cost=cost of bagles+cost of cream cheese
7.00=0.75b+1.29
subtract 1.29 from both sides
5.71=0.75b
divide both sides by 0.75
7.6=b
he can't buy a fraction of a bagle so round down
7=b
he bouth 7 bagles
