Student price tickets to a movie are $1 and non-student tickets are $2. 350 tickets are sold and the total amount made is $450.
How many non-student tickets were sold?
1 answer:
S + n = 350.....s = 350 - n
s + 2n = 450
350 - n + 2n = 450
n = 450 - 350
n = 100 <=== there were 100 non-student tickets sold
