Javier teaches yoga classes at his community center. In a 60-minute class last night, he taught 30 poses. Today, he has a 30-minute class. If he teaches at the same rate, how many poses will Javier teach in today's class?

I'm guessing 15 poses because 30/60 half and 15/30 half so basically in the 60 minute lesson Javier spend 1 minute teaching them how do to each pose, so in the 30 minute lesson he'll spend 1 minute on the other poses.

Step-by-step explanation:

this was a little confusing and sorry if i dont make since

207/8 is the right

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
