Use the elimination method to solve the following system of equations. x+y=1 and x-y=-6 . the system has a single solution. the solution set is (x, y) (type an ordered pair, using integers or fractions.) b. there are infinitely many solutions. the solution set is (type an equation. type your answer in standard form.) c. the solution set is the empty set.

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
