debra works at Walmart. her regularly hour wage is $8.50a.) she regularly works 40 hours per week. what would be her annual salary?b.) if she works 50 weeks each year at this rate, what would be her annual salary?

Respuesta :

a) You know that she works 40 hours per week.

You know that there are 365 days in a year and there are 7 days in a week. Then, the number of hours she regularly work per year, can be found as following:

[tex]\begin{gathered} \frac{40}{7}=\frac{x}{365} \\ \\ \end{gathered}[/tex]

Where "x" is the number of hours she regularly work per year.

Solving for "x", you get:

[tex]\begin{gathered} (365)(\frac{40}{7})=x \\ \\ x=2,085.71 \end{gathered}[/tex]

Debra's regularly hour wage is $8.50 and, then, multiply the value of "x" by $8.50 in order to calculate her annual salary (in dollars):

[tex](2,085.71)(8.50dollars)\approx17,728.54dollars[/tex]

b) If she works 50 weeks per year, you can set up the following proportion to find "x":

[tex]\frac{50}{7}=\frac{x}{365}[/tex]

Solving for "x", you get:

[tex]\begin{gathered} (365)(\frac{50}{7})=x \\ \\ x\approx2,607.14 \end{gathered}[/tex]

Multiply the value of "x" by $8.50 in order to calculate her annual salary (in dollars):

[tex](2,607.14)(8.50dollars)\approx22,160.69dollars[/tex]

The answers are:

a) $17,728.54

b) $22,160.69
