For some constants A and B, the rate of production, R(t), of oil in a new oil well is modelled R(t)=A+Be^(-t)sin(2πt) where t is the time in years, A is the equilibrium rate, and B is the "variability" coefficient. Find the total amount of oil produces in the fi...

let x represent one of the shirts and then set up the equation 3x-(3x*.3)=63 because there are 3 shirts and after you find the total of the shirts you would usually subtract the percentage of that total from the total. The equation equals 63 from what was given. then solve 3x-...
