At the bake sale a total of 540 cookies and brownies were sold for a total of $750.00 Brownies cost $ 1.00 each and cookies cost $0.35 each. Write a system of equations for this situation

x + y = 540

x + 0.35y = 750

Step-by-step explanation:

The x represents the brownies and y represents cookies. They both add up to 540, hence the first equation. Also, the prices add up to $750. The x doesn't need a coefficient since it is a dollar a piece. But, since the cookies cost 35 cents a piece, they need a coefficient.

answer: 1, 3 and 5 are correct

step-by-step explanation:

range is infinite on both x and y axis positive and negative
