You are helping with decorations for your grandparents' 50th wedding anniversary. You have to buy the streamers and balloons. The streamers cost $\$ 3$ per roll, and the balloons cost $\$ 5$ for a group of 10. You only have $\$ 66$ to spend on the decorations.How many rolls of streamers and groups of balloons can you buy? Let x represent streamers and y represent balloons. Write a linear inequality to represent this situation. $3x+5y\leqslant 66$ $3x+5y\lt 66$ $3x+5y\geqslant 66$ $3x+5y\gt 66$
