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.
