Answer:

Colleen has $300 and Jimmy has $703

Step-by-step explanation:

x=10 weeks

Answer:

Based on a 15 week semester, by the end Jimmy will have accumulated in his savings account $49 more than Colleen

Step-by-step 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
