Answer:
$7.00
Step-by-step explanation:
The discount is 75% off. To answer this question, multiply n (the original price) by (1.00 - 0.75): 0.25n = $1.75.
Solving this for n, we get $7.00
Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)
Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points
Plug in the given points:
(y2 - y1) / (x2 - x1)
(12 - 4) / (6 - 2)
8 / 4
= 2
So, the slope of the line is 2.
Let b=the number of boxes, c=cost of the pens
The expression that represents the total cost of the pens if a box costs 4 dollars and then she gets a 1 dollar discount for every additional box is c(b)=3b+1. We got this from the original equation c(b)=4+(4-1)(b-1). Simplify this and you will get c(b)=3b+1.
