Kristen has been eating $150 per week by babysitting. She has been working to save 20 percent of each weeks earning. If she continues to save the same amount each week, how many weeks will it take her to save $180

Answers

Answer: it takes her 6 weeks to save $180

Step-by-step explanation:

Kristen has been earning $150 per week by babysitting. This means she earns a total of $150 every week for babysitting. She has been working to save 20 percent of each weeks earning. This means she saves 20/100 × the amount she earns every week.

She saves 20/100× 150

= 0.2 × 150 = $30

She continues to save this amount in order to save a total of $180.

Number of weeks it will take her to save $180

= total amount / amount saved in a week

= 180 / 30 = 6 weeks
