Answer:
at least 434 programs
Step-by-step explanation:
Data provided in the question:
Cost of printing the programs = $150 + 0.50/program
Selling cost of the program = $2
Desired profit = at least $500
Let the number of programs sold to earn profit of $500 be 'x'
Now,
Total cost = $150 + $0.50x
Total revenue = $2x
Profit = Total revenue - Total cost
$500 ≤ $2x - ( $150 + $0.50x )
or
$500 ≤ $2x - $0.50x - $150
or
$1.5x ≤ $650
or
x ≤ 433.33
or
x ≤ 434
