Answer:
£ 294
Step-by-step explanation:
Let Caroline get "c"
Sarah get "s"
ad
Gavyn get "g"
Now,
Caroline gets TWICE as Sarah, so we write:
c = 2s
Also,
Sarah gets THREE times as Gavyn, so we can write:
s = 3g
or
g = (1/3)s
Also, total is 980 between 3 person, so we can write:
c + s + g = 980
We replace this equation with first 2 (in bold) to get:
[tex]c + s + g = 980\\(2s) + s + (\frac{1}{3}s)=980\\3\frac{1}{3}s=980\\[/tex]
Now, we solve for s:
[tex]3\frac{1}{3}s=980\\\frac{10}{3}s=980\\s=\frac{980}{\frac{10}{3}}\\s=980*\frac{3}{10}\\s=98*3\\s=294[/tex]
Sarah gets £ 294
