Aleksandr [31]

The answer is C.
Here's why, nPr = n!/(n-r)!. Plug in 7 for n and 3 for r. And you get 7!/(7-3)!.
Thus, 7!/4! = (7*6*5*4*3*2*1)/(4*3*2*1), which simplifies to 7*6*5 = 210

The price of ticket last year is $ 1231.65

Solution:

Given that,

This year, Sophia paid $1,071 for season tickets to her favorite baseball team , which is 15% cheaper than last year

To find: Price of season ticket last year

Let the price of season ticket last year be "x"

Therefore, according to question

Price of ticket this year is 15 % cheaper than price of ticket last year

1071 = price of ticket last year - 15 % of 1071

1071 = x - 15 % of 1071

Solve the above expression for "x"

$1071 = x - 15 \% \times 1071\\\\1071 = x - \frac{15}{100} \times 1071\\\\1071 = x - 0.15 \times 1071\\\\1071 = x - 160.65\\\\x = 1071 + 160.65\\\\x = 1231.65$

Thus price of ticket last year is $ 1231.65
