Answer:
96 points
Step-by-step explanation:
Ratio problems can be solved like this:
Let x equal an unknown value.
Now, we can write an equation.
7x + 10x +12x = 232
We want to find 12x, so we have to find x first. We can simplify our equation to:
29x = 232
Now, divide both sides by 29.
x=8
We then solve for 12x by multiplying 8 and 12, and get 96 points.
The formula to find markup amount

A new car has a sticker price of $22,150, while the invoice price paid on it was $18,780.
Original price of new car = $18,780
Sticker price of new car = 22,150
Change in price = 22,150 - 18,780 = 3370
Markup = 
= 
= 0.179446
Markup percentage = 0.179446 * 100 = 17.94%
6: x= 45 and it is acute
7: x= 45 and it is also acute
18 is not a function because a function is when exactly ONE x value is paired with ONE y value.
19 is not a function because of the same logic for number 18
