velikii [3]

Answer:

The money earned by Drea was $\$225$

The money earned by Sajini was $\$200$

Step-by-step explanation:

Let

x------> money earned by Drea

y------> money earned by Sajini

we know that

$x+y=425$ -----> equation A

$x=y+25$ ----> equation B

substitute equation B in equation A

$(y+25)+y=425$

solve for y

$2y=425-25$

$y=400/2=\$200$

Find the value of x

$x=y+25$ ----> $x=200+25=\$225$

using a graphing tool

solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is $(225,200)$
