A contractor charges $1200 for 100 square feet of roofing installed. at this rate, how much does it cost to have 1100 square feet installed

Step-by-step explanation:

If it cost $1200 to install 100 square feet of roofing, then it will cost $13200 to have 1100 square feet installed.

$1200/ 100 square feet         multiply 11 on both sides

$13200/ 1100 square feet

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

it is probably the graph on the bottom right.
