All you have to do is substitute 2 and 7 in for x in the function.
f(2) = 2(2) + 7
= 11
f(7) = 2(7) + 7
= 21
Answer:
The answer to your question is 5 weeks
Step-by-step explanation:
Data
Ryan Miles
$150 $50
each week = $40 each week = $60
x = savings
y = time in weeks
Process
1.- Write an equation for Ryan savings
x = 40y + 150
2.- Write an equation for Miles savings
x = 60y + 50
3.- Solve the system by Equality
40y + 150 = 60y + 50
- Solve for y
40y - 60y = 50 - 150
-20y = -100
y = -100 / -20
y = 5
4.- Conclusion
After 5 weeks, they will have the same amount of money.
