Question

5 each month marla pays a $30 cell phone bill from her back account. at the end of one year, what is the change in the amount of money in marla’s account because of her cell phone bill? write a multiplication equation to represent the problem. explain what the product represents.

Explanation:

Step1: Identify the values

Marla pays $30 per month, and there are 12 months in a year. Since paying the bill means money is deducted, we can represent the monthly payment as -$30 (negative because it's a decrease in her account balance).

Step2: Write the multiplication equation

The total change in her account balance over a year is the monthly change multiplied by the number of months. So the equation is $-30\times12$.

Step3: Calculate the product

$-30\times12 = -360$. The product -360 represents the total amount of money deducted from Marla's account over the course of one year due to her cell phone bill.

Answer:

The multiplication equation is $-30\times12 = -360$. The product -360 represents the total decrease (in dollars) in Marla's account balance over one year because of her cell phone bill.
