Answer:
6 weeks
Explanation:
Janelle is saving $6 per week, so to save $50, she will need:
$50 - $20 = $30 more
To find out how many weeks it will take her to save $30 at a rate of $6 per week, we can divide:
$30 / $6 per week = 5 weeks
Therefore, it will take Janelle 5 more weeks to save $50, for a total of 5 + 1 = 6 weeks.
