Answer:
The money earned by Drea was [tex]\$225[/tex]
The money earned by Sajini was [tex]\$200[/tex]
Step-by-step explanation:
Let
x------> money earned by Drea
y------> money earned by Sajini
we know that
[tex]x+y=425[/tex] -----> equation A
[tex]x=y+25[/tex] ----> equation B
substitute equation B in equation A
[tex](y+25)+y=425[/tex]
solve for y
[tex]2y=425-25[/tex]
[tex]y=400/2=\$200[/tex]
Find the value of x
[tex]x=y+25[/tex] ----> [tex]x=200+25=\$225[/tex]
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 [tex](225,200)[/tex]
see the attached figure

Answer:
Drea: $225
Sajini: $200
Step-by-step explanation:
D + S = 425
D = S + 25
S + 25 + S = 425
2S = 400
S = 200
D = 200 + 25 = 225
