Answer:
a = 250x + 1300
Step-by-step explanation:
We have pairs (5, 2550) and (8, 3300)
Find the rate of change:
(3300 - 2550)/(8 - 5) =
750/3 =
250
$250 is the amount added to savings account every month
Initial amount was:
2550 - 5*250 =
2550 - 1250 =
1300
Since the change is linear and we have y-intercept and slope, we can show the amount after x months as:
a = 250x + 1300
