A neon sign at the local grocery store flashes red, blue, and green. The sign changed colors 55 times in one day. Of those 55 times, the sign flashed red 22 times and blue 11 times.

• Green is just as likely to appear as red and more likely than blue to appear.

• Green is just as likely as red or blue to appear.

• Green is not as likely as red or blue to appear.

• Green is not as likely as blue to appear but is as likely as red to appear.

A plumber charges $65 for a consultation fee and x dollars for labor per hour. Write an equation that would represent this situation if it took the plumber 5 hours to fix a problem and the total cost is $240. Find the plumber's hourly charge for labor.

• 5x + $65 = $240; x = $35

• 5x – $65 = $240; x = $61

• $65 – 5x = $240; x = –$35

• 5x + $240 = $65; x = $45

Kaylee is picking up pizza for her family. She ordered 3 small pizzas and 2 large pizzas. Each small pizza has x slices and each large pizza has 2x slices.

Which expression is NOT equivalent to the number of slices of pizza that Kaylee will have altogether?

• 7x

• 2 (x) + 3 (2x)

• 2 (2x) + 3 (x)

• 3x + 4x
