A quadratic equation is written in the form
Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).
This makes the first option the correct choice since the expansion of the equation gives
The theater must sell more than 35 tickets to earn at least $1000.
Step-by-step explanation:
Cost of one student ticket = $9.50
Tickets already sold = 70
Cost of 70 tickets = 70*9.50 = $665
Worth to be made by selling tickets = $1000
Let,
x be the number of tickets to be sold.
According to statement;
The theater wants to earn $1000 minimum, therefore,
Cost of one ticket*Number of tickets to be sold + cost of 70 tickets > Total worth to be earned
Dividing both sides by 9.50
Rounding off to nearest whole number
x>35
The theater must sell more than 35 tickets to earn at least $1000.
