In finding the minimum amount of time that Brandon can swim is to add the quotient of the distance to swim and its velocity and the quotient of the difference of 250 and the distance cover in running and its velocity. The minimum time is 43.33 seconds
Well, we knew that from 0 to 1 you add '1', from 1 to 4 you add '3', from 4 to 9 you add '5', from 9 to ? you add '7'!
So 9+7=16.
16 to ? you add 9! 16+9=25
The next 2 terms are 16 and 25.
5
because distance formula gets you square root of 25 which is 5
For 10 hours of job Gerald earns 8*10=80$
For 11 hours Gerald earns 8*10+9n. n - number of working hours over 10 hours.
if Gerald work 16 hours, then he work 6 hours after 10, so n=6

2(4.25 + 2.25) = 2(6.50) = 13...this is the cost without the tax
13 + 0.05(13) = 13 + 0.65 = 13.65 <=== total with the sales tax added
