Answer:
<u>The number of copies that will make it worth the discount card is 250.</u>
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)
<u>The number of copies that will make it worth the discount card is 250.</u>

The answer to this problem is letter d
Answer:
Option b and d.
Step-by-step explanation:
Given equation : -5x + 4y > -7
Putting the values of x and y one by one in the options,
a) Putting x as 6 and y as 4.
=> -5(6) + 4(4) > -7
=> -30 + 16 > -7
=> -14 > -7
This doesn't satisfy the inequality, hence this couldn't be the ordered pair.
Similarly,
b) Putting x as 5 and y as 5.
=> -5(5) + 4(5) > -7
=> -25 + 20 > -7
=> -5 > -7
This satisfies the inequality, hence this is the ordered pair.
c) Putting x as 3 and y as 2.
=> -5(3) + 4(2) > -7
=> -15 + 8 > -7
=> -7 > -7
This doesn't satisfy the inequality, hence this couldn't be the ordered pair.
d) Putting x as -2 and y as -4.
=> -5(-2) + 4(-4) > -7
=> 10 - 16 > -7
=> -6 > -7
This satisfies the inequality, hence this is the ordered pair.
