There are 38 houses in a new community available with two floor plans. Floor plan x sells for $175,000 and Floor plan y sells for $200,000. The total worth of all available homes are $7,200,000. Write an equation that illustrates this situation.
Part A: x+y=38
Part B: 175,000x + 200,000y=$7,200,00.
Is this correct?
Need to also use elimination to determine how many houses are available with floor plan x and floor plan y? Explain how the answer was arrived.
