Question

For 15 weeks , Sue put the same of money in a jar. The she took $9 out to spend on a friend 's birthday present. She had $21 left. How much did she put in each week

Answer 1

$2 is the correct answer add to get starting total then divide by fifteen to get how much per week

Answer 2

Let's set the amount of money that Sue put in each week as x.

The amount of money she would have saved in 15 weeks is 15x. However, she took 9 dollars out and had 21 left over.

Set up an equation.
15x-9=21
15x=39
x=2

Sue put in $2 every week.

Hope this helps!
