Question

Sam is saving money to buy a hockey stick that costs $222. Sam has $22 and will save $10 each week. How many weeks will it take Sam to save enough money to buy the hockey stick? Write an equation to represent this situation. Use w to represent the number of weeks.

Answer 1

20 weeks, 22+10w

Explanation:

See, if Sam will save $10 each week, that would be 10 into the number of weeks, or 10w.

Now, he already has $22, so we can add 22 to 10w, and our final equation would be 22+10w.

Therefore, the number of weeks required would be:

22+10w = 222

10w = 200

w = 20

:)

Answer 2

Answer:
W = (222-22):10
(Minus because he already have 22, and divided by ten, because he earns that much.)

W = 200:10

W = 20

Answer: He need 20 weeks to buy.

Or Idea 2:

22 + 10w = 222
