how to do? William wanted to buy a shirt and a tie for her father as a birthday gift. 5 ties cost the same as 2 shirts. 5 ties and 2 shirts cost a total of $2660. How much more did a shirt cost than a tie?

We want to know s - t = ?

 

We know:

2s = 5t

2s + 5t = 2660

 

We can substitute in our ratio (first equation) into the second equation twice:

 

2s + 2s = 2660

5t + 5t = 2660

 

Solve and find that shirts cost 665, ties cost 266. Put that in our very first question and we get the answer - shop at a different store cause this one's for millionaires (or $399 😅)
