arlik [135]

Answer:

A public communications director would make $1,196,800 over a period of 20 years.

Step-by-step explanation:

The median salary of an engineer is $73,400 per year.

Piper has researched that a public communications director makes $13,560 less than this. (so we need to take this amount from the salary of an engineer)

Therefore, we would have that a public communications director would make

73,400 - 13,560 = $59, 840 per year

Now, the problem asks us how much a public communications director will make over a period of <u>20 years</u>, thus, we have to multiply the amount she will get per year by 20.

Thus, over 20 years she would make: <u>59,840 x 20</u> = $1,196,800
