The answer is 10/3, the whole number form of it is 3 1/3 :)
The answer is -4.5
To solve these types of problems it's best to work backwards.
-2 - 16 = -18
4 x (n) = -18
n = -18/4
n = -4.5
The slope of 6x + 2y = 4 is
y = -3x + 2
112-88 = 24
they save $24 per month
so 650/24 = 27.083
so it will pay for itself in 27.083 months, round up to 28 months
