Let's say a is the original price and b is the price with a 32% discount.
a*0.68=b
Wchi is close to
1.47058 * b = a
Our new price is $391 so...
1.47058 * 391 = a
a = $575
Answer:
What is it?
Step-by-step explanation:
Row 15 has 41 seats, and the entire section has 493 seats.
We can write the explicit formula for an arithmetic sequence to represent this, since we add 2 each time:
13+2(n-1)
Using 15 for n,
13+2(15-1) = 13+2(14) = 13+28 = 41
To find the total number of seats, we evaluate the sum

Using technology to evaluate this sum, it is 493.
