Micah was given $200 for his birthday. Each week he spends $15 on comic books. In how many weeks will his birthday
money be gone?
Create multiple representations (table, graph, and equation) for the relationship between the weeks since Micah's birthday
and how much money he has left. How does each representation show the solution to the problem?

Answer:

14 weeks

Step-by-step explanation:

Simply divide 200 by 15, then round up because the answer should be a full week:

200 / 15 = 13.3333 ≈ 14 weeks

For an equation, let x be weeks passed and y be money left. Since the money is spent at a constant rate, the equation will have a constant slope, and the y intercept is 200, since at no money spent, Micah has $200:

y = -15x + 200

For a ratio table, it might look something like this:

weeks  :  money

0       :      $200

1        :      $185

2       :      $160

3       :      $145

Answer:

v= -15x + 200 x 213.33 weeks 6= 15x + 200 the answer is 13
