Answer:
Based on a 15 week semester, by the end Jimmy will have accumulated in his savings account $49 more than Colleen
Explanation:
Jimmy's Equation: Y = $64 + 25x
Colleen's Equation Y = $120 + 18x
X = # Of Weeks
Y = Total Savings Account
If the average semester is 15 weeks long, then you would plug x = 15
Jimmy:
Y = 64 + 25(15)
Y = $439
Colleen:
Y = 120 + 18(15)
Y = $390
