Answer:
The equation given in the question matches the situation C.
Step-by-step explanation:
A. The amount that Cindy paid for books was 15% of p i.e. it is only
B. The amount is given to a charity after saving 15% of p. That means if p is the amount of charity, then there were a savings of 15% of p.
Therefore, the total charity payment after savings = p - 15% of p =
C. The amount that Sandy paid for a shirt with 15% tax on p.
Therefore, if the price of a shirt is p, then total payment of Sandy after tax is = p + 15% of p =
Hence, the equation given in the question matches the situation C. (Answer)

Step-by-step explanation:

Answer:
y=14
Step-by-step explanation:
Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.
plug in 25 in 2x and you would get 50°
Since the sum of a triangle is 180° you could set up an equation 
Then, add 50+50=100+10=110
then you would then have 
subtract 110 from 180, leaving you with 70

then divide and you would get 14
Check:
5(14)+10+50+50= 180
If the total amount of points in a test is 140, and we want to find 10% of those points, we can do the following to figure out how much points the question is worth...
140 points x 10% = 140 x 0.1 = 14 points for the short-answer quesion.
