Question

Madeline wants to buy a camera for $200 dollars. Her weekly allowance is $15. If she saves $10 each week toward the cost of the camera, how many weeks will it take Madeline to save enough to buy it?

Answer 1

Answer:

20 weeks

Step-by-step explanation:

To answer, we can use an expression for this problem. We know that Madeline wants to get a total of $200 to get the camera, and she gets $15 a week, but wants to save $10 a week. Lets say that the variable x equals the amount of weeks it will take Mdeline to save enough:

10x = 200

So, if we just isolate the variable x by dividing 10 on both sides like so:

10x = 200

/10     /10

x = 20

We get 20 as our answer, therefore concluding that Madeline will have to save for 20 weeks

Hope this helps :)

Answer 2

Answer:

14 weeks.

Step-by-step explanation:

15x-10=200

add 10 to both sides

15x= 210

divide by 15

x=14 .
