[tex]\large\boxed{2\,\text{cycling outfits}}[/tex]
In this question, we're trying to see how many cycling outfits that Mr. Trager could buy.
To find how many he could buy, we have to figure out the amount of money he spent.
To do this, we would add the values of the things he bought.
[tex]273.98+3*7.23+42.36=338.03[/tex]
Mr. Trager had already spent $338.03
Lets see how much money he has left over:
[tex]500-338.03=161.97[/tex]
He has $161.97 left to spend.
We know that each cycling outfit costs $78.12 and he has $161.97 left to spend.
[tex]78.12*2=156.24[/tex]
Two outfits cost $156.24
This means that he could buy 2 cycling outfits.
