kiruha [24]

Answer:

$A=42000(1.04)^n$

Step-by-step explanation:

This is a compound interest formula expressed as:

$A=P(1+i)^n$

Where

$n$ is time in years
$i$ is the rate of interest
$A$ is the accumulated amount after n years
$P$ is the initial amount.

#We substitute the given values to determine amount after n years as follows:

$A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n$

Hence, the amount earned after n years of her career is given by $A=42000(1.04)^n$

Tresset [83]

Question:

Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?

Answer:

Ana raised $ 12.5

Solution:

From given question,

First day walk = 11 miles

Second day walk = 14 miles

Let us first calculate the total distance she walked

Total distance = first day walk + second day walk

Total distance = 11 + 14 = 25 miles

Thus she walked for 25 miles

Given that,

She raised $0.25 for each 1/2 mile that she walked

$\frac{1}{2} \text{ mile} = 0.25 \text{ dollars }$

Therefore, for 1 mile we get,

$\frac{1}{2} \times 2 \text{ mile} = 0.25 \times 2 \text{ dollars }\\\\1 \text{ mile } = 0.5 \text{ dollars }$

Now calculate for 25 miles

$25 \text{ mile } = 25 \times 0.5 = 12.5 \text{ dollars }$

Thus she raised $ 12.5
