Question

Each Saturday, a gym holds a 45-minute yoga class. The weekday yoga classes last 30 minutes. The number of weekday classes varies. Last week, the yoga classes totaled 165 minutes. How many weekday yoga classes were held?

 

 

 

 

ASAP Please?

Answer 1

Let y be yoga classes, and we get the equation:

30y + 45 = 165

We move the 45 to the other side:

30y = 120

Divide by 30:

y = 4

So there were 4 weekday yoga classes
