A vendor will sell sandwiches for $2 each. The cost for supplies is 25cents for each sandwich, plus $10 parking each day. How many sandwiches must he sell to make a profit of $60 each day?
---
Cost(x) = 10 + 0.25x dollars per day
----
Revenue = 2x dollars per day
----
Profit = Revenue - Cost = 2x - [10+0.25x] = 1.75x -10
-----
Equation:
1.75x-10 = 60
1.75x = 70
x = 40 (# he must sell to make profit of $60)
