step-by-step explanation:

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

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

the answer is
