Answer 1

Answer:

Option A) 144.87 miles

Step-by-step explanation:

Given that:

Charlie drove miles each day:

156.5 miles;

217.7 miles;

108.3 miles;

141.6 miles;

97.9 miles;

179.7 miles;

112.4 miles.

We know that average formula says:

Average = Sum of all quantities/ total quantities

As there are total of 7 days in a week So:

Average = (156.5 miles + 217.7 miles + 108.3 miles + 141.6 miles + 97.9 miles + 179.7 miles +  112.4 miles.) / 7

Average = 1014.1/7

Average = 144.87 miles

i hope it will help you!
