Kaira's gross pay is $4,633. Her deductions total $1,009.13. What percent of hergross pay is take-home pay?Round to the nearest

Delvig [45]

Answer:

$\text{ 78\%}$

Explanation:

Here, we want to get the percentage of the gross pay is the take-home pay

Mathematically, we have to divide the take-home pay by the gross pay and multiply it by 100%

Her take-home pay is the difference between her gross pay and her deductions

We have this as:

$\text{ 4633 - 1009.13 = \$3,623.87}$

We have this as:

$\frac{3623.87}{4633}\text{ }\times\text{ 100 \% = 78\%}$

Solve for s. 1/2 s = 7/2. A 1/7. B 2/7. C 3. D 7.

fenix001 [56]

Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

$\frac{1}{2} s = \frac{7}{2} \\ \\\frac{(\frac{1}{2}s)}{\frac{1}{2}} = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{7}{2} * \frac{2}{1} \\ \\\\s = 7$

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
