Question

Emily spent $55 from her savings on a new dress.Explain how to describe the changes in Emily's savings balance in two different ways.

Answer 1

Emily's savings=x 1.x-55=n


N=New emily's savings 2.N-55=x

Answer 2

The two ways are:

Emily's savings balance = x - $55

Emily's savings balance % =
`\frac{55}{\text{initial amount}}* 100`

Explanation:

Consider the provided information.

Emily spent $55 from her savings on a new dress.

We need to find two different ways to describe the changes in Emily's savings balance.

Let x is the amount she had initial.

She spent $55 so use a negative sign to represents spent amount.

Thus, Emily's savings balance = x - $55

or, we can show this with the help of percentage.

We can calculate how much is 55$ from the total amount.

This can be represented as:

Emily's savings balance % =
`\frac{55}{\text{initial amount}}* 100`

Hence, the two ways are:

Emily's savings balance = x - $55

Emily's savings balance % =
`\frac{55}{\text{initial amount}}* 100`
