Homework Statement
The total cost for 88 adult tickets was $_293_. Because the printing machine was not functioning well, the first and the last digits of the 5-digit number were missing. If the cost for each ticket is $P, where P is an integer, find the value of P.
Homework Equations
i think factor theorem should be used.
The Attempt at a Solution
attempt 1
cost = 10000a + 2930 + b
88P = 10000a + 2930 + b
attempt 2
try to make x = 100
and make divider 88 to become 100-12 = 88, thus divider becomes x-12
generate a general equation
f(x) = a(x^2) + 2930 + b
then because it can be wholly divided by x-12,
f(12) = 0
144a + 2930 + b = 0
i don't seem to be getting anywhere, please help
