Question 766644
s = 15, how many shots
h = how many hits
m = how many misses


Account for money:  {{{+50*h-20*m=120}}} cents
{{{5h-2m=12}}} when divided both sides by 10.


s=15, so {{{15=h+m}}}


Solve the system:
{{{highlight(5h-2m=12)}}} and {{{highlight(h+m=15)}}}


Could go like,
{{{m=15-h}}},
then
{{{5h-2(15-h)=12}}}
{{{5h-30+2h=12}}}
{{{7h=12+30=42}}}
{{{h=6}}} meaning {{{m=9}}}

RESULT: 6 hits and 9 misses.
