Answer:
I used the function normCdf(lower bound, upper bound, mean, standard deviation) on the graphing calculator to solve this.
- Lower bound = 1914.8
- Upper bound = 999999
- Mean = 1986.1
- Standard deviation = 27.2
Input in these values and it will result in:
normCdf(1914.8,9999999,1986.1,27.2) = 0.995621
So the probability that the value is greater than 1914.8 is about 99.5621%

Step-by-step explanation:
Apparently, your system of equations is supposed to be ...
We can multiply the first equation by 2 and subtract the second equation:
2(4b -3h) -(5b -6h) = 2(64) -(44)
3b = 84
b = 28
Using the first equation, we can find the price of a hand towel:
4b -64 = 3h
h = (4/3)(b -16) . . . . . divide by 3 and factor out 4
h = (4/3)(28 -16) = 16
Bath towels cost $28 each, and hand towels cost $16 each.
