(c) s = $187.5, g = $212.5

Step-by-step explanation:

(a) Let's call

s: money earned by Seiji

g: money earned by Gavin

Together they earned a total of $400. Mathematically:

s + g = 400 (eq. 1)

Gavin eamed $25  more than Seiji. Mathematically:

25 + s = g (eq. 2)

(b) see picture attached

(c) From the picture we can see that:

s = $187.5

g = $212.5
