Best answer gets

it costs $100 to rent the bowling alley, plus $4 per person. the cost for any number (n) of people can be found using the expression 100 + 4n. the cost for 10 people equals $ (input whole number only.)

Well we start by turning that "n" into 10 in 100 + 4n, and that 4n means we gotta multiply, so we multiply 4 X 10 to get 40. now we just add 100 + 40 to get our answer, which is $140

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
