Answer:
The number of copies that will make it worth the discount card is 250.
Step-by-step explanation:
1. Let's review the information provided to answer the question correctly:
Cost per copy without discount = US$ 0.08
Cost per copy with discount = US$ 0.05
Cost of discount card = US$ 7.50
2. How many copies will make it worth the discount card?
For finding out this number of copies, we will use the following equation:
x = Number of copies that will make it worth the discount card
0.08x = 0.05x + 7.50
0.03x = 7.50 (Like terms)
3x = 750 (Multiplying by 100 at both sides)
x = 250 (Dividing by 3 at both sides)
The number of copies that will make it worth the discount card is 250.
