You have $270 in your bank account. You plan to save $80 from your paycheck each week. Which graph shows your bank account balance at the end of each week?
the one rising from 270 with a slope of 80
To answer this question, we can create a table to track the bank account balance at the end of each week.
Week | Bank Account Balance
---- | -------------------
0 | $270
1 | $270 + $80 = $350
2 | $350 + $80 = $430
3 | $430 + $80 = $510
4 | $510 + $80 = $590
We can now plot these points on a graph. On the x-axis, we plot the number of weeks, and on the y-axis, we plot the bank account balance.
The graph will start at the point (0, $270) and increase by $80 each week. The line connecting these points will be a straight diagonal line.
To find the bank account balance at the end of each week, we can start by subtracting $80 from $270.
1st week: $270 - $80 = $190
2nd week: $190 - $80 = $110
3rd week: $110 - $80 = $30
4th week: $30 - $80 = -$50
Now, we can plot these values on a graph to visualize the bank account balance at the end of each week.
The x-axis represents the weeks, and the y-axis represents the bank account balance.
Starting at week 0 with $270, we have the following data points:
Week 0: $270
Week 1: $190
Week 2: $110
Week 3: $30
Week 4: -$50
Plotting these points on a graph and connecting them with lines, we get a decreasing trend in the bank account balance over time.
So the line graph would show the bank account balance decreasing from $270 in week 0 to -$50 in week 4.
