4. Shelton earns an hourly wage at a grocery store. The following expression represents Shelton’s take home pay after taxes, social security, and his health care plan are deducted. Let x represent the number of hours Shelton worked. 10.25x − 0.21(10.25x)

a) Which term represents Shelton’s total pay before deduction?

b) Shelton wants to save $1,675 for a new laptop. If Shelton saves 25% of his take-home pay, how many hours will he need to work to meet his savings goal?

a)  Shelton’s total pay before deduction: 10.25x

b)  To meet savings goal he'll have to work 827.415869 hours.

Step-by-step explanation:

Take-home pay:

  10.25x − 0.21(10.25x)

  10.25x − 2.1525x

  8.0975x

Save 25% for new laptop:

  .25(8.0975x) = 1675

     2.024375x = 1675

     x = 827.415869 hours

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
