That'd be : 28.8 . I hope this helps. This is it step by step.
60/x=100/48
<span>(60/x)*x=(100/48)*x </span>
<span>60=2.08333333333*x
</span>(2.08333333333) to get x
<span>60/2.08333333333=x </span>
<span>28.8=x </span>
<span>x=28.8</span>
<span>Jill has $30 and Maddie has $60. Jill saves $4 per week and Maddie saves $2 per week. How long will it be before Jill and Maddie have the same amount of money?</span>
