Darrel loaned his friend $2500 to him with his business. if his friend pays darrel back in 1 year with 15% simple interest, how much will he owe darrel altogether?

$2875

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

, where P is the principal amount , r is the rate of interest and t is the time period.

Given: Principal amount = $2500

Rate of interest = 15%=0.15

Time period = 1 year

Now, the simple interest gained by Darrel after 1 year will be :-

Now, the total amount his friend owed altogether=

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
