Question 1163141
<pre>
Instead of doing it for you, I am doing another problem exactly like yours,
with the numbers changed.  I'm doing this one instead:

A T-shirt costs 6 times as much as a singlet. For $900, a trader can buy 34
more singlets than t-shirts. How much does a T-shirt cost?
<pre>
A singlet costs $x
A T-shirt costs $6x

For $900, a trader can buy $900/($x) = 900/x singlets
For $900, a trader can buy $900/($6x) = 180/x T-shirts

{{{900/x = 180/x + 34}}}

Multiply through by x

{{{900 = 180 + 34x}}}

{{{720 = 34x}}}

{{{21.17647059 = x}}}

A singlet costs $21.18.

A T-shirt costs $6x = $127.08
