solve the equation

Question

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

The freshman and sophomore classes at Fairview High School are decorating floats for homecoming. The freshmen have already spent $265 on their float, plus they need to buy floral sheeting that costs $10 per roll. The sophomores, who have spent $272 so far on theirs, still need to purchase vinyl grass at $9 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 many rolls will each class be buying? How much will each class spend in total?

By buying  rolls, the two classes will each spend $ in total.

Answer 1

F=265+10R

S=272+9R

F=S

265+10R=272+9R

R=# of rolls and F=S= amount spent by each class.

You solve it from here.
