Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
Answer: $42042.50
Step-by-step explanation:
We need to use algebra and equations.
A = P x (1 + (R/n)/100)^nt
our amount (A) is $72K
the number of times we compound the money (n) is 12 (12 months in a year, 'compounded monthly')
our rate (R) is 9 (9%)
our time (t) is 6 (6 years)
we need to find our principal/initial amount (p)
72000 = p x (1 + 0.0075)^12x6
p = $42042.50
Use combination
probability = (11C1 + 7C1)/28C2
probability = (11+7)/378
probability = 18/378
probability = 1/21
3/4a>-16
Multiply by the reciprocal of 3/4 on each side to get only a on one side of inequality.
a> -16 x (4/3)
That can be simplified to:
a > -64/3
a > -21 1/3
Hope this helps :)
