miskamm [114]

Given :

James puts $3,500 into a savings account that earns 2.5% simple interest.

He does not touch that account for 3 years.

To Find :

The new balance of the account be after 3 years.

Solution :

Interest on $3500 after 3 years is :

I = \dfrac{P_o\times r\times t}{100}\\\\I = \dfrac{3500\times 2.5\times 3}{100}\\\\I = \$262.5

So, new balance of the account after 3 years is $( 3500+262.5 ) = $3762.5  .

Hence, this is the required solution.

Answer:

f(x) = 3 + 5x

Step-by-step explanation:

For this problem, we can see a simple pattern whereas x increases by 1, y is increasing by 5.

This means that f(0) = 3.

And to create the function, we simply use f(0) summed with the increasing 5 multiplied by the input x.

Hence, we will create the function equation:

f(x) = 3 + 5x

Cheers.
