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
enters 10 in cell a4. which formula should eric use?

B

Step-by-step explanation:

To complete the question, here are the answer choices:

A)  =A1*A2*A3*A4

B)  =A1*A2+A3+A1*A4

C)  =A1*(A2+A3+A1)*A4

D)  =A1*A2+(A3+A1)*A4

We first need to multiply A1 and A2, this will give weight of passengers.

To get weight of luggage, we multiply A1 and A4.

We also need the checked weight to add to that, which is in A3. So then we add up A3 with those 2.

So we will get

A1*A2 + A1*A4 + A3

This is given in a different order in Option B. Hence, option B is right.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
