Question

Nicole is very interested in photography. She wants to purchase a new camera. It costs $900. She gets paid $400 every two weeks. Write a goal for her.

Answer 1

Let, the number of weeks, required for buying that camera = x
She earns = $400 per week
Then in x weeks, she will earn = 400x

Now, 400x = 900
x = 900 / 400
x = 9/4

In short, She needs 2 1/4 weeks or if she gets paid after a whole week, then 3 weeks [ 'cause you'd have round-it off to the nearest greater value ]

Hope this helps!
