Matching Algebraic Equations to Scenarios

Josh put his baseball card collection into 3 binders. He put the same number of cards into each binder. If Josh has a total of 246 baseball cards, which equation could show c, the amount of cards in each binder?

• 3 - c = 246

• c - 3 = 126

• c + 3 = 126

• c x 3 = 246

After eating 57 jellybeans, Jasmine has 341 left in her jar. Which equation can be used to find h, the amount of jellybeans Jasmine had in her jar before eating the 57 jellybeans?

• 341 - 57 = h

• h - 57 = 341

• 341 + 57 = h

• 341 - h = 157

Hunter sold 54 hamburgers for $3 each and 25 hot dogs for $2 each. Which equation can be used to find t, the total amount of money Hunter made from selling the hamburgers and hotdogs?

• t = (54 x 25) + (3 x 2)

• t = 54 + 25 + 3 + 2

• t = (54 x 3) + (25 x 2)

• t = (54 + 3) + (25 - 2)

Jackie received a gift of $100 for her birthday. She purchased 5 t-shirts that each cost $17. Which equation can be used to find a, the amount of money Jackie has left from her birthday money?

• a = $100 - 5 - $17

• a = $100 x (5 x $17)

• a = $100 + (5 x $17)

• a = $100 - (5 x $17)
