A certain theater has 100 balcony seats. For every $2 increase in the price of a balcony seat above $10, 5 fewer seats will be sold. If all the balcony seats are sold when the price of each seat is $10, which of the following could be the price of a balcony seat if the revenue from the sale of balcony seats is $1,460 ? | [
"$18",
"$18.6",
"$14",
"$17"
] | B | I solved it as follows:
10+2(x) = 100 -5(x)
x= 12
Equation should be (10+$2*x)(100-5x)=1,460, where x is the # of times we increased the price by $2. (10+$2*x)(100-5x)=1,460 --> (5+x)(20-x)=146 --> x=4.3 or x=10.7 --> price=10+$2*4.3=$18.6 or price=10+$2*10.7=$31.4.
