There are no real solutions to solve Z. If there may be a typo or something, there are no solutions.
We have that
x------------------> <span>represent the number of hours Steven babysits
y----------------- > </span><span>represent the amount he charges
for x=6 hours
y=</span><span>$37.50 ----------------> y/x=37.5/6=6.25
</span>for x=8 hours
y=$50---------------------> y/x=50/8=6.25
therefore
y=6.25x
the answer is
y=6.25x
16/17 is the answer. you just add the numerators since they have common denominators!
