Bela started studying how the number of branches on her tree grows over time. Every 2.9 years, the number of

kati45 [8]

Answer:

The required function that models the number of branches t years since Bela began studying her tree is

number of branches = $60(1.83)^{\frac{t}{2.9} }$

Step-by-step explanation:

Let t be the time in years

Initially Bela's tree had 60 branches.

therefore the function that can be used to model the number of branches after t years will be given by

number of branches( after t years) $= 60\times(1 + \frac{83}{100})^{\frac{t}{2.9} } = 60(1.83)^{\frac{t}{2.9} }$

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.
