Question

Cindy works part time a day earns $5.75 an hour. One year she worked 50 weeks and averaged 12.4 hours of work per week. About how much money did she earn that year?

Answer 1

We know that she earns 5.75 $  per hour.

She worked  12.4 hours per week that year, so for each of those weeks she earned:

5.75 * 12.4 = 71.30 $

From the information we have, she worked for 50 such weeks in that year.

So to get the total amount earned, we multiply the earnings of one week by the total number of weeks she worked, so:

71.30 * 50 = 3,565.

She earned a total of  3,565 $ that year.
