Final answer:
To find the number of bands, divide the total number of band members by the average number of dancers per band. In this case, there were 26 bands in the last carnival.
Step-by-step explanation:
To find the number of bands, we need to divide the total number of band members (8,060) by the average number of dancers per band (310). This can be done using the formula:
Number of bands = Total number of band members / Average number of dancers per band
Plugging in the values, we get:
Number of bands = 8060 / 310 = 26
Therefore, there were 26 bands in the last carnival.
