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
First, we focus on the part with the "t" variable. Then we subtract the values with variables which gets us 3t. Finally, we can't do anything with the +2, so our solution is 3t+2.
