The price of a bushel of corn is currently $3.20, and the price of a peck of wheat is $5.80. The price of corn is increasing at a constant rate of 5*x cents per day while the price of wheat is decreasing at a constant rate of squareroot2*(x) - x cents per day. What is the approximate price when a bushel of corn costs the same amount as a peck of wheat?
320 + 5x = 580 - x*2^(1/2) + x
x = 260/(4+2^(1/2))
plugging this back into equiation
my guess is E (I don't have a calculator)
why did you assume that only 1 day is involved ...i.e. prices decrease & increase for 1 day only ?
This is a nasty question or something is missing here
Assume prices become same after N days
320 + N(5x) = 580 - N(xsqrt2 - x )
N = 260 / x(4+sqrt2)
There are 2 variables and only 1 equation.
Something seems to be wrong or missing.
