Answer:
- S = 30 +16t
- J = 55 +11t
- $110
Step-by-step explanation:
The y-intercept in the equation is the initial amount in savings. The slope is the amount saved per week.
S = 30 +16t
J = 55 +11t
__
These are equal when ...
30 +16t = 55 +11t
5t = 25 . . . . . . . . subtract 30+11t
t = 5
S = 30 +16·5 = 30 +80 = 110
After 5 weeks, both Savannah and Jacob will have saved $110.
