Answer:
x = 5
Step-by-step explanation:
The equation of a line is given by :
y=2x+2.5
Where
y is cost and x is number of tickets
Put y = $12.5 in the above equation
So,
12.5=2x+2.5
10 = 2x
x = 5
So, he can purchase 5 tickets.
The answer would be 1437 due to the zero property. Therefore you only add the other two numbers.
