Explanation:
First, you need to add all of the numbers to find the total budget. The total budget is <u>$1,116.</u> Then, to find the percentages, you need to divide each sections' money by the budget. For example, for 'contributions', you will do $175.76/$1,116 and get 0.157. But, this is a decimal. To make it into a percentage, you move the decimal point 2 spaces to the right. .157 = 15.7% So, for the 'contributions' section, the answer is 15.7%. Another example. For the 'housing' section, the amount was $350.84. Divide that by $1,116.
Move the decimal point <em>2 spaces to the right</em> -- 31.4%

let the number of
- adults be x
- children be y
Total number of people : adults + children
- x + y = 240
- x = 240 - y - [1]
Total money earned from adults :
- 6 × x = 6x
Total money earned from children :
- 2 × y = 2y
Therefore, total money = money earned from each Adult and children.
- 6x + 2y = 1200 -[2]
Now, let's plug the value of x from equation [1] into equation [2]
- 6 (240 - y) + 2y = 1200
- 1440 - 6y + 2y = 1200
- -4y = 1200 - 1440
- -4y = - 240
- y = 60
let's plug the value of y in equation [1]
- x = 240 - y
- x = 240 - 60
- x = 180
Hence, we get :
- total adults = x = 180
- total children = y = 60
Correct option is C

Step-by-step explanation:
Given that angle A is in IV quadrant
So A/2 would be in II quadrant.
sin A = -1/3
cos A =
(cos A is positive since in IV quadrant)
Using this we can find cos A/2
