Let x=Don's present age
2x=Chris's present age
next year:
<span>x+1=Don's age
</span><span><span>2x+1=Chris's age
(x+1)+((2x+1)=4(x-1) (next year the sum of their ages will be four times as much as Don's age last year.)
x+1+2x+1=4x-4
x=6
2x=12
Don's present age=6
Chris's present age=12 </span><span>
</span></span>

To determine the cost per second can be calculated by converting the given unit in terms of second. The conversion factor that will be used is 1 minute is equal to 60 seconds. Also, use proper dimensional analysis as shown below.
R = ($12,800 / minute) (1 minute / 60 seconds)
R = $213.33/seconds
Therefore, one second of advertisement during prime time costs $213.33.
