Question 175576
</pre><font size=4><b>
Let {{{x}}}=total money for his b-day
Remember: "Total money=Total expenses"
It follows, Working Eqn,{{{x=(1/2)x+highlight(5)}}}----->{{{system(store1=1,store2=1,store3=1,store4=1,store5=1,5dollars)}}}
Now, that "half of his money"--->{{{highlight((1/2)x)}}} is  not telling us what portion for every store he spend it, right? Anyway it's an expense so we need to add it to the Total Expenses.
Then, the total expenses= half of the money he had, {{{(1/2)x}}} + $1 for every store.
Continuing,
{{{x-(1/2)x=5}}} combine similar terms
{{{(1/2)x=5}}} cross multiply
x=$10 -------->Original Money (ANSWER)
Check via Working Enq:
{{{10=(1/2)10+5}}}
{{{10=5+5}}}
{{{10=10}}}
*If not stisfied, post it again, and somebody might have a better understanding of it.
Thank you,
