Anthony paid a 20% tip on a $15 dinner bill. Liam paid a 15% tip on his dinner bill, and left the same dollar amount as the tip Anthony left. How much did Liam's dinner cost, before the tip?
+876 20% of $15 is \(\frac{1}{5} \cdot 15 = $3\) tip. 15%= \(\frac{3}{20}\). \(\frac{3}{20} x = 3\Rightarrow \frac{1}{20} x = 1\Rightarrow x=20\)
Liam's dinner cost $20.
