He will receive $480 in interest in the first year.
A) Amount of money earned by seji = s
Amount of money earned by Gavin = g
So, equation would be: s+g = 425
B) Solving the system: s+g = 425
we know, g = s+25
Substitute it into the equation:
s+s+25 = 425
2s = 400
s = 200
so, g = 200+25 = 225
C) Graph for the equation, Mark (s,g) = (200,225) then, draw the line from the origin.
D) Seiji earned = $200
Gavin earned = $225 [ Solved in B part ]
Hope this helps!
20/100 = 0.2
0.2 * 39.50 = 7.90
They should leave a $7.90 tip.
5/100 = 0.05
39.50 * 0.05 = 1.975 and rounds to 1.98
