Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
If the total doesn't include the tip, and the tip isn't included in how much the families each spent, they spent $41.75 each on their food bill.
If the total includes the tip, each family spent $34.25 on their food bill and $7.50 on the tip for the waitress.
If the total doesn't include the tip, but you want to include the tip, each family spent $49.25 on the food bill AND tip.
167/4 = 41.25
(167-30)/4 = 34.25
30/4 = 7.50
(167+30)/4 = 49.25
