Question

two-way table setup
scenario:
suppose we have a dataset detailing the number of electric and gasoline cars sold in urban and rural areas.

car type/area	urban	rural	total
gasoline	?	?	?
total	?	?	400

assume the following data points:

• urban electric: 120 cars
• rural electric: 80 cars
• urban gasoline: 150 cars
• rural gasoline: 50 cars

what is the total number of cars sold in the rural area?
options: 150, 130, 200, 180

Explanation:

Step1: Identify rural car sales

We need to find the total number of cars (electric + gasoline) sold in rural areas.

Step2: Sum rural electric and gasoline

Rural electric cars sold: 80. Rural gasoline cars sold: 50.
Total rural cars = \( 80 + 50 = 130 \).

Answer:

130
