Answer:
Noah and Jace will have the same amount of money saved 4 weeks after the beginning of the year. This is the point of intersection on the graph of the two functions.
Step-by-step explanation:
To graph the functions that represent the amount of money Noah and Jace have saved, we can set up their savings functions as follows:
Noah's savings function (NN):
NN(tt) = $90 (initial savings) + $10 (weekly savings) * tt
Jace's savings function (JJ):
JJ(tt) = $50 (initial savings) + $20 (weekly savings) * tt
Now, let's graph these functions:
Noah's Savings Function (NN):
Initial savings (y-intercept): $90
Weekly savings rate (slope): $10
Jace's Savings Function (JJ):
Initial savings (y-intercept): $50
Weekly savings rate (slope): $20
To find the number of weeks after the beginning of the year until Noah and Jace have the same amount of money saved, we can set the two functions equal to each other and solve for "tt":
NN(tt) = JJ(tt)
$90 + $10 * tt = $50 + $20 * tt
Now, solve for "tt":
$90 - $50 = $20 * tt - $10 * tt
$40 = $10 * tt
tt = $40 / $10
tt = 4
