Ответ:
14 weeks.
Step-by-step explanation:
15x-10=200
add 10 to both sides
15x= 210
divide by 15
x=14 .
Ответ:
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 :)
