Multiple Choice

Mackenzie collects stickers in a sticker book.

She has 127 animal stickers. She has 35 fewer scratch-and-sniff stickers than animal stickers. She has 9 more star stickers than scratch-and-sniff stickers.

Which equation represents s, the number of star stickers in Mackenzie’s collection?

• (127 + 35) x 9 = s

• (127 - 35) ÷ 9 = s

• (127 - 35) + 9 = s

• (127 + 35) - 9 = s

Multiple Choice

Best Burgers sells hamburgers, cheeseburgers and veggie burgers.

They make 221 cheeseburgers and 186 hamburgers every day. They make half as many veggie burgers as hamburgers each day.

Which equation can be used to find b, the total number of burgers made at Best Burgers everyday?

• b = (221 + 186) + (186 x 2)

• b = (221 - 186) + (186 ÷ 2)

• b = (221 + 186) - (186 ÷ 2)

• b = (221 + 186) + (186 ÷ 2)

Multiple Choice

Darwin earned $95 helping his grandfather with chores.

He earned $40 raking leaves and $15 washing the car. The rest of the money was earned from pulling weeds.

Which equation can be used to find w, the amount of money in dollars Darwin earned from pulling weeds?

• w + 40 - 15 = 95

• 40 + 15 + w = 95

• 40 - 15 - w = 95

• w - 15 + 40 = 95
