Tamia started with 500 dollars in her savings account. Every month, Tamia spends 50 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
0 500
1 450
2 400
3 350
Next, let's represent this situation with a graph. The x-axis represents time in months, and the y-axis represents the number of dollars in the account.
Now, let's represent this situation with an equation. Let's say the amount in the account after x months is represented by y. The equation can be represented as:
y = 500 - 50x
This equation represents the decrease of 50 dollars each month from the initial amount of 500 dollars in Tamia's savings account.
