Derek has a bank account that pays 4.1% simple interest. He deposits $910 and leaves it in for 2.5 years. How much interest does he earn.​

After 2 and a half years, Derek's bank account will have earned interest of $ 93.27.

Step-by-step explanation:

Given that Derek has a bank account that pays 4.1% simple interest, and he deposits $ 910 and leaves it in for 2.5 years, to determine how much interest does he earn, the following calculation must be performed, knowing that simple interest is not added to the initial capital:

(910 x 0.041) x 2.5 = X

37.31 x 2.5 = X

93.275 = X

Thus, after 2 and a half years, Derek's bank account will have earned interest of $ 93.27.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
