Answer:
The amount of reward that Sophia receives is [tex]\$13[/tex]
Step-by-step explanation:
Let
x------> amount of reward that Sophia receives
y-----> amount of reward that Isabella receives
we know that
[tex]\frac{x}{y}=\frac{1}{8}[/tex]
[tex]x=\frac{1}{8}y[/tex] ------> equation A
[tex]x+y=117[/tex] -----> equation B
Substitute equation A in equation B
[tex]\frac{1}{8}y+y=117[/tex]
[tex]\frac{9}{8}y=117[/tex]
[tex]y=117*8/9=\$104[/tex]
Find the value of x
[tex]x=\frac{1}{8}(104)=\$13[/tex]
