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?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-shirtsMultiply through by x A singlet costs $21.18. A T-shirt costs $6x = $127.08 Edwin
