A group of scientists studied the effect of a chemical on various strains of bacteria. Strain A started with 1200 cells and decreased at a constant rate of 3000 per hour after the chemical was applied. Strain B started with 4000 cells and decreased at a rate of 200 per hour after the chemical was applied. When will the strains have the same number of cells? Explain
