step A: Brian entry cost=$5
Brain purchase total cards=x
cost of total cards= 4*total number of cards
let total cost for the day=y
equation=> total cost= entry cost + cost of total cards
y=5+4x
Step B: total amount=$29
cards purchase=?
according to the Step A
Y=5+4x
29=5+4x
29-5=4x
24=4x
24/4=x
6=x
he purchased 6 cards .
Step C: if he have $65 than how many cards he can purchase=?
according to the Step A
Y=5+4x
65=5+4x
65-5=4x
60=4x
60/4=x
15=x
he can purchase total 15 cards .
