Two parking attendants are required to park cars for each type A lot, while just one can handle each type B lot. Of the ten lots that will be used tonight, six are type A and four are type B. How many parking attendants are required for tonight's event?

Answer 1

16 because 2x6=12 4x1=4 so 12+4=16

Answer 2

Answer: 16 parking attendants are needed.

Explanation: The formula to solve for the number of parking attendants needed is 2A + B, where the variables are the identifying letter of each parking lot.

In order to solve the problem you need to substitute the number of lots into the formula:

(2 x 6) + 4 = 16

16 parking attendants are required for the evening’s event.
