Answer:

{1.2}^{n}  \times 2.5

Step-by-step explanation:

it's simple my dear friend.

first, she runs 3 miles per week.

so in

{a}^{(n - 1)}   \times b

b is 3. the initial value.

increasement by 20% means she runs 1.2 times than before.

\frac{100 + 20}{100}  =  \frac{120}{100}  =  \frac{12}{10}  = 1.2

then a=1.2

so we have now:

{1.2}^{(n - 1)}  \times 3 \\  =   {1.2}^{n}  \times  \frac{3}{1.2}   \\  =  {1.2}^{n}  \times 2.5

and we got it!

Which problem would you use the following proportion to solve for? = what is 40% of 24? what percent is 24 of 40? twenty-four is
ser-zykov [4K]
First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
