Question

2. Kervins is $28 in debt because he borrowed money to buy food after school. He plans to pay back his debt at a rate of $7 per week. Which of the following equations best describes how many weeks it will take Kervins to pay off his debt?(a) 28 ÷7 = 4(b) - 28÷ - 7 = - 4(c) - 28 ÷- 7 = 4(d) - 28÷7 =-4

Answer 1

- 28 ÷- 7 = 4 (option C)

Step-by-step explanation:

Debt = $28

Amount required to pay back the debt per week = $7

let the number of weeks required = y

Remember, because it is a debt, it will be negative

Debt = - 28

weekly payment = -7

-28 = -7y

Divide both sides by -7:

-28/-7 = y

y = 4

The equation that best describes how many weeks it will take Kervins to pay off his debt:

- 28 ÷- 7 = 4 (option C)
