Trina started with 250 dollars in her savings account. Every month, Trina spends 25 dollars from her savings account at the grocery store. Represent this situation with a table, a graph, and an equation.
Let’s start by representing this situation with a table. Start by finding the amount in the account after 0, 1, 2 and 3 months.
Time in months Number of dollars in the account
0
1
2
3
Time in months Number of dollars in the account
0 250
1 225
2 200
3 175
Next, let's represent this situation with a graph. The x-axis will represent the time in months, and the y-axis will represent the number of dollars in the account.
Now, let's represent this situation with an equation. Let t represent the number of months and A represent the number of dollars in the account.
A(t) = 250 - 25t
This equation represents the amount of money in Trina's savings account after t months.
