Lin and Han's families provide money for their school lunch accounts.
• Han starts with $100 in his account. He spends $15 each week
on lunches.
• Lin starts with $25 in her account and does not spend any of it.
Her family adds $10 each week to her account.
1. At the end of 4 weeks, who has more money in their account?
2. After how many weeks will Han and Lin have the same amount
of money in their lunch accounts?

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) equation for Han:  y = 100 - 15w

y = 100 - 15(4)

y = 100 - 60

y = $40 after 4 weeks

equation for Linn:  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

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

no i do not : ( what is it?
