Question

James started with 600 dollars in his savings account. Every month, James spends 60 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

Time in months Number of dollars in the account
0 600
1 540
2 480
3 420

Next, 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.

Lastly, let's represent this situation with an equation. Let's denote the number of dollars in the account after t months as A(t). Then the equation would be:

A(t) = 600 - 60t

This equation represents the amount in James' savings account after t months, taking into account the 60 dollars he spends every month.
