You borrowed $2,500 from your grandmother. You agreed to pay back the loan with a single payment at the end of five years. The interest rate was set up at 2% per year. How much will you owe your grandmother when you pay off the loan

$2,750

Explanation: This is a simple interest problem, we calculate thus:

Principal = $2,500

Time = 5 years

Rate = 2%

Formula:

I = (P x R x T)/100

I = (2,500 x 2 x 5)/100

I = 25,000/100

I = 250.

Therefore the amount that will be owed at the end of 5 years is:

$2,500 + $250 = $2,750.

$27,500

Explanation:

We can us simple interest to solve the question because it is the tool that be used in this cases

To solve this , we have the formula of simple interest as

I = (Principal ×rate × time )÷100

We given the following as;

Principal = $2,500

Rate = 2%

Time = five (5) years

Substituting the values into the formula we have

I = ($2,500× 2× 5)÷100

I = $25,000÷100

I = $250

Now the total money that will be returned to grandmother will be addition of principal and simple interest which is

= $2,500+$250

= $27,500

i know right it’s not fair some people are just so rude unlike you your actually trying to get to know people and i think that is very kind

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
