T= total
<span>Money spent is: </span>
48+ 1/3 (T-48) = 1/2 T
One equation for one unknown, solve:
48 + 1/3 T -1/3*48= 1/2 T
48 - 16 =1/2 T- 1/3 T
32= 1/6 T
T= 6*32
<span>T=192
</span>192-48=144 money left after watch
1/3*144=48 third of leftover, spent on pen
<span>144-48=96 left which is half of 192. </span>
So
in this problem we can see that there will be 60 people at the party.
Following the conditions for this event that state the following:
$750 for up to 30 people and every extra person pays $20. To show
that the cost will be $1350 in total we simply do this:
For
30 people we have $750 dollars. Now every other person after pays
only $20. That means that another the other 30 people will pay in
total only $600.
If
we add them we get: $750 + $600 = 1350. This shows that the cost will
be $1350.
