The freshman and sophomore classes at Union Grove High School are decorating floats for homecoming. The freshmen have already spent $263 on their float, plus they need to buy floral sheeting that costs $49 per roll. The sophomores, who have spent $407 so far on their float still need to purchase vinyl grass at $13 per roll. Both classes plan to buy the same number of rolls, since they have the same area to cover. By coincidence, the two floats will have the same total cost in the end.
How much will each class spend in total?
How many rolls will each class be buying?
