Matching Algebraic Equations to Scenarios

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)

What is the value of a in this equation?

(Include a dollar sign in your answer)

a = $100 - (5 x $17)

Pat spent $24 of her allowance on iTunes. After making her purchases, she had $73 of her allowance left. Which equation could be used to find k, the amount of Pat's allowance before her iTunes purchases?

• $73 - $24 = k

• k - $24 = $73

• $24 - k = $73

• $73 - k = $24

What is the value of k in this equation?

(Include a dollar sign in your answer)

k - $24 = $73

What is the value of c in this equation?

c x 3 = 246
