Question 788084
${{{x}}}= one month rent.
${{{(1/2)*x}}}= half of a month's rent = security deposit
${{{x+(1/2)x=1725}}} = total amount to be paid to the landlors before moving in
Solving:
{{{x+(1/2)x=1725}}}
{{{(1+1/2)x=1725}}}
{{{(3/2)x=1725}}}
{{{(2/3)(3/2)x=(2/3)1725}}}
{{{x=2*1725/3}}}
{{{x=3450/3}}}
{{{highlight(x=1150)}}}
The monthly rent is $1150.
 
You could also express half a month's rent as {{{0.5x}}}.
Then,
{{{x+0.5x=1725}}}
{{{(1+0.5)x=1725}}}
{{{1.5x=1725}}}
{{{x=1725/1.5}}}
{{{highlight(x=1150)}}}
