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 [tex]\frac{15p}{100} = 0.15p[/tex]
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 = [tex]p - \frac{15p}{100} = p - 0.15p = 0.85p[/tex]
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 = [tex](p + \frac{15p}{100}) = p + 0.15p = 1.15p[/tex]
Hence, the equation given in the question matches the situation C. (Answer)
