On a tray there are X cupcakes and 4 times as many cookies as there are cupcakes. Which equation represents the total number of cookies, Y, on the tray?

• Y=4X
• X+Y=4
• 4XY
• X=4Y

2X+2+X+4+2X is equivalent to

• 5X+6
• 10X
• 2X+6+X
• 4X+6X

Maria and Jessica are working comparing and sharing the answers they got to the problem 2(3X+3Y) and Maria has 6X+6Y and Jessica has 8XY. Who is right and why?

• Maria because 2(3X)+2(3Y)=6X+6Y

• Maria because 2(3X)+2(3Y)=2+3X+2+3Y

• Jessica because 2(3X)+2(3Y)=4(3xy
