Lin and Han's families provide money for their school lunch
Julli [10]

Answer:

1) after 4 weeks, Lin has more with $65

2) after 3 weeks they both have same amount

Step-by-step explanation:

let 'w' = number of weeks

1) <u>equation for Han</u>:  y = 100 - 15w

y = 100 - 15(4)

y = 100 - 60

y = $40 after 4 weeks

<u>equation for Linn</u>:  y = 25 + 10w

y = 25 + 10(4)

y = 25 + 40

y = $65 after 4 weeks

2) 100 - 15w = 25 + 10w

    75 - 15w = 10w

    75 = 25w

     w = 3 weeks
