Row 3 $15
Row 4

Use the table to help you solve these problems. Explain or show your reasoning.(try using unit rate)
1. Noah bought 4 tacos and paid $6. At this rate, how many tacos could he buy for $15?
2. Jada’s family bought 50 tacos for a party and paid $72. Were Jada’s tacos the same price as Noah’s tacos?
