If i have a pay rate of $21.00 and marked up 78.7% and made a 10% profit. how did i get $41.28?

Virty [35]

Step-by-step explanation:

Since we have given that

Amount of pay rate =$21

If she marked up by 78.7% , so it becomes

$78.7\%\text{ of}\$21\\\\=\frac{78.7}{100}\times \$21\\\\=\$16.527$

So, our amount for pay rate becomes

$21+16.527\\\\=\$37.527$

Now, he said he made a profit of 10%,so it becomes

$10\%\text{ of }37.527\\\\=\frac{10}{100}\times 32.527\\\\=\$3.7527$

So, our new pay rate becomes

$37.527+3.7527\\\\=\$41.2797$

This is the step through which we can get $41.28.

3 1/3 feet are cut off a board that is 12 1/4 feet long.How long is the remaining

laiz [17]

Answer:

$8\frac{11}{12}$

Step-by-step explanation:

In order to answer this question you will have to subtract 3 1/3 from 12 1/4 by turning the mixed fractions into improper fractions, finding the common denominator, (CD) then subtracting the numerators.

$12 \frac{1}{4} - 3\frac{1}{3}$

Turn the mixed fractions into improper fractions:

$12\frac{1}{4} = \frac{49}{4}$

$3\frac{1}{3} = \frac{10}{3}$

$\frac{49}{4} -\frac{10}{3}$

Find the common denominator:

$4\times3=12$

$3\times4=12$

$CD=12$

$49 \times 3 =147$

$=\frac{147}{12}$

$10\times4=40$

$=\frac{40}{4}$

Now subtract the numerators:

$147-40=107$

$=\frac{107}{12}$

Turn the improper fraction into a mixed fraction:

$\frac{107}{12} =8\frac{11}{12}$

$=8\frac{11}{12}$

Hope this helps.
