The <em><u>correct answer</u></em> is:
C.) old price was $170, new price is $159.12
Explanation:
The original price was $136. For a 25% markup, this means the amount of markup is 0.25(136) = 34. This makes the new price 136+34 = $170.
When they mark the price down to a 17% markup, this means the price is 0.17(136)+136 = 23.12+136 = $159.12.
Answer:
30 kilometers
Step-by-step explanation:
I just looked at it and knew it was 30 k as the longest
This is how I knew:
let's convert every unit into meters
90cm = 0.9m
40m = 40m
30km = 30000m
40mm = 0.04
easy :)
good luck

Answer:
Step-by-step explanation:
This is called a 'System of equations'.
Say that you have these two expressions, and the unknown is "b".
5b = y
4b+2 = y
Now we can solve two ways; graph it or solve it.
Solving it, we can see that they both equal y, so:
5b=4b+2
move 4b to the left side by subtraction:
(5b-4b) =2
b = 2
let's see what y equals when b = 2
5 * 2 = y
10 = y
Graphing it we see they intersect, or solve at
(2,10) or b=2, y=10
Hope this helps!
That point does not satisfy either inequality.
You can tell it does not satisfy the first portion, due to it being under the shaded line. Secondly, the dotted line goes through it, but that fact that it is dotted makes it not included.
