Final answer:
Ben will pay approximately $0.42 for each pen from Acme Wholesale and approximately $0.61 for each pen from Grant Supply Company.
Step-by-step explanation:
To find out how much Ben will pay for each pen, we can set up a system of equations using the information given.
Let's assume the price of one pen is P dollars.
From Acme Wholesale, we know that 100 pens plus 200 pencils cost $125. So, we can write the equation:
100P + 200P = 125
Similarly, from Grant Supply Company, we know that 500 pens plus 200 pencils cost $425. So, we can write the equation:
500P + 200P = 425
Simplifying both equations, we get:
300P = 125
700P = 425
Dividing both sides of the equations by their respective coefficients, we can solve for the price of one pen:
P = 125/300 = $0.4167
P = 425/700 = $0.6071
So, Ben will pay approximately $0.42 for each pen from Acme Wholesale and approximately $0.61 for each pen from Grant Supply Company.
