You invest $1000.00 in one account and $3,000.00 in another account. both accounts have the same interest rate over the same amount of time. how will the interest earned compare?

a they will earn the same amount of interest
b the $3,000.00 account will earn 3x the amount of interest
c the $1,000.00 account will earn one-half the amount of interest
d the $3,000.00 account will earn one-third the amount of interest 《《《

B: The $3,000.00 account will earn 3x the amount of interest.

Step-by-step explanation:

Let us solve this by taking rate and time as 5% and 5 years respectively.

Also let us assume that it is simple interest.

Case 1:

p = 1000

r = 5% or 0.05

t = 5

Interest = p x r x t

Interest earned =

= $250

Case 2:

p = 3000

r = 5% or 0.05

t = 5

Interest earned =

= $750

We can see that the interest earned in case 2 is times the interest earned in case 1.

So, the correct option will be :

The $3,000.00 account will earn 3x the amount of interest.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

it is x equals 3   plese mark me really need it
