I think it's B (Sorry if im wrong)
Answer:
$58,560
Step-by-step explanation:
First step: set up your proportion equation. Keeping the percents on the bottom, I set it up as $48,000/100% = $x/122%. I'm writing it as 122% rather than 22% so we don't have to add the increase in price to the original price later. You can see that, in order to get from 100 to 48,000, you need to multiply by 480, so you can do this to 122 to get x. Your teacher might, instead, want you to cross multiply. Do what's expected of you. Either way, your result should be $58,560. Check that it makes sense by checking that it's an increase and that it looks reasonable for the amount of the increase and you're done.

Answer:
<A = 124
Step-by-step explanation:
Remark
This figure has 7 angles. Therefore it can have 5 lines drawn from 1 vertex to all the other vertexes. That gives you 5 triangles. See the diagram below to see the result of what I have just described. The sum total of all the interior angles is 5 * 180 = 900
Equation
Add the seven given angles from your figure to equal 900
(9x - 2) + (10x + 2) + 165 + 100 + (5x + 83) + (12x + 18) + 138 = 900
Solution
Now add all the like terms on the left together.
- Terms Containing "x"s: 9x + 10x + 5x +12x = 36x
- Terms not containing "x"s: -2 + 2 + 165 + 100 + 83 + 18+ 138 = 504
So this simplifies to
36x + 504 = 900 Subtract 504 from both sides
36x + 504 - 504 = 900 - 503 Do the subtraction
36x = 396 Divide by 36 on both sides
x = 396/36 Do the division
x = 14
Answer
But you want angle A.
<A = 9x - 2 = 9*14 - 2 = 126 - 2 = 124
Let us write an equations
1st pizza place costs 9.95 + x dollars, where x is the number of toppings
2nd pizza place 6.95 + 1.5 y dollars, where y is the number of toppings
We are interested when they are equal:
9.95 + x = 6.95 + 1.5y
3= 1.5y - x
As the questions asks for the same ammount of toppings, x=y
3= 1.5y - x this becames
3=0.5 x
x=6
Lets check
9.95+6=15.95
6.95+6*1.5=15.95
So the answers is 6
