Step-by-step explanation:
Each of the printing companies have their own advantages. APlus Printing has a lower setup fee and PrintMore has a lower cost for each poster printed. We can find out at what number of posters are the 2 costs the same.
Let x be the number of posters.
We have $20 + $0.1x = $55 + $0.05x.
=> $0.05x = $35
=> x = 700
Hence we can give a conclusion:
- If Elliot is printing less than 700 posters, he should use APlus Printing.
- If Elliot is printing more than 700 posters, he should use PrintMore.
- If Elliot is printing exactly 700 posters, he should use either company.
