Answer:
b. 13
Step-by-step explanation:
163-9=154 to get the amount of people coming
154÷12=12.833 is the amount of tables needed if each seat 12 and 154 people are coming
round up to 13 because you cant have 12.833 tables
We can't see the rest of the chart
Answer:
To do this in my head: 60km = 40km+20km
So 40km/8km = 5
40 k is approximately 5x5miles = 25 miles
20k is half that or 12.5 miles
60 is about 25+12.5 miles
or 37.5 miles
