Answer:
$94.99
Step-by-step explanation:
-Given the tip is 18% and the bill before tip is $161
-We calculate the total bill(inclusive of tip):
[tex]Total=Bill+Tip\\\\=161+0.18(161)\\\\=\$189.98[/tex]
-Assuming the the split was in equal proportion, then each family will pay 50%of the total bill:
[tex]Split \ Ratio=1:1\\\\Bill/Family=\frac{1}{2}\times 189.98\\\\=\$94.99[/tex]
Hence, each family paid a total of $94.99
