Question

Ariana wants to make $207 she makes $10 a week how many weeks and months does she need to work to make $207

Answer 1

It takes 5 months and 1 week (21 weeks)

Answer 2

Answer:

4 months and 4 weeks  

Step-by-step explanation:

(a) Calculate the weeks

In one week, Ariana earns $10.

To earn $207, the weeks she must work are:

Weeks = $207 × (1 wk/$10)

            = 20.7 wk  

Ariana must work 20.7 weeks.

(b) Convert to months and weeks

There are 52 weeks and 12 months in a year

So, 52 weeks = 12 mo nths

20.7 wk = 20.7 wk × (12 mo/52 wk)

             = 4.777 mo

Now, convert 0.777 mo back to weeks.

0.770 mo × (52 wk/12 mo) =  3.37 wk

Presumably, Anna won't get paid until the end of the week, so

She must work 4 months and 4 weeks  

(Note: On average there are 4⅓ weeks in a month, so she is working just a little less than 5 months.)
