Answer: the total number of coupon books sold is 20.
Step-by-step explanation:
Let x represent the number of coupon books that Mario sold.
Let y represent the number of coupon books that Luigi sold.
Apparently, Mario is a much better salesperson, because he sold 4 times as many coupon books as Luigi. This is expressed as
x = 4y
If Luigi sold 12 fewer coupon books than Mario, the expression would be
x = y + 12 - - - - - - - - - - -- -1
Substituting x = 4y into equation 1, it becomes
4y = y + 12
4y - y = 12
3y = 12
y = 12/3
y = 4
x = 4y = 4 × 4
x = 16
The total number of coupon books that the two boys sold is
4 + 16 = 20

Answer:
a. $629.10
b. $635.80
c. $6.70
Step-by-step explanation:
The first thing we need to do is turn these percentages into decimal values by dividing them by 100, this would make 10% into 0.10 and 15% into 0.15. Now we can make the following equations to calculate the total by multiplying the 100 pens by the individual pricer per pen, and then multiplying that product by the 1 minus the discount percentage.
A) (100 * 6.99) * (1 - 0.10) = x
699 * 0.90 = x
$629.10 = x
B) (100 * 7.48) * (1 - 0.15) = x
748 * 0.85 = x
$635.80 = x
C) 635.80 - 629.10 = $6.70
The difference is $6.70 more for the 100 pens in the second store.
