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

Answer:
Total number of people in the stadium = 520
Step-by-step explanation:
Let the total number of people in the stadium = x
Since, 25% of the fans are teenagers, number of teenagers in the stadium
= 25% of x
= 
= 0,25x
If the number of teenagers in the stadium = 130
0.25x = 130
x = 
x = 520
Therefore, total number of fans in the stadium = 520.
