Eric works for an airline, and he needs to calculate the weight of passengers and luggage before takeoff. the number of
passengers is in cell a1. the airline uses an average weight of 180 pounds per person, so eric enters 180 in cell a2. the
weight of the checked luggage is entered in cell a3. each passenger is alloted 10 pounds for carry-on luggage, so he

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
