Question

Emily spent $55 from her savings account on a new dress explain how to describe the change in emilys savings balance in two different ways

Answer 1

you can either express the decrease that happened in the account savings by integers. To do this you simply subtract 55$ from the initial amount in the account. This is expressed as:
initial amount - 55$

or, you can express the decrease in the form of percentage by calculating how much is 55$ from the total amount. This is expressed as:
(5/initial amount) x 100
