Apple juice costs $2 per bottle, and cranberry juice costs $3 per bottle. Tamiko has at most $18 with which to buy drinks for a club picnic. She lets x represent the number of bottles of apple juice and lets y represent the number of bottles of cranberry juice. Then she graphs the inequality 2x+3y≤18, as shown below. If Tamiko buys 5 bottles of apple juice, how many bottles of cranberry juice can she buy? Express answer as an inequality.
