Question

Dylan started with 300 dollars in his savings account. Every month, Dylan spends 30 dollars from his 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

Answer 1

To find the amount in the account after 0, 1, 2, and 3 months, we can subtract 30 dollars for each month from the initial amount of 300 dollars.

Time in months Number of dollars in the account
0 300
1 270
2 240
3 210

Now, let's represent this situation with a graph.

The x-axis will represent time in months and the y-axis will represent the number of dollars in the account. The points on the graph will be (0, 300), (1, 270), (2, 240), and (3, 210).

Lastly, let's represent this situation with an equation.

The equation to represent the situation would be:
Amount in the account = 300 - 30t

where t represents the number of months.
