Question

Which equation best represents the revenue for selling n raffle tickets at $3.50 each?

r = n + 3.5
r + n = 3.5
r = 3.5n
r = 3.5/n

Answer 1

you multiply the price by the number of tickets sold to obtain revenue

Answer 2

define P = 3.5
define N = number of tickets sold

R = P * N

where R is defined as revenue

Answer 3

So C ?

Answer 4

is it?

Answer 5

Yeah, I think.

Answer 6

Am I wrong?

Answer 7

3A typically means A+A+A or 3*A

100B means B + B + B ...... until you add the 100th B or in short 100 * B

so if we are talking about 3.5N that would mean 3.5 * N (and whatever may the value of N will be)

Answer 8

remember that those letters are just placeholders
