Naomi wants to take yoga classes. She can take classes at the high school for a one-time fee of $20 plus $10 per class. She can join the local gym for $50 and take classes for $5 per class. Which statement is true about the average cost for the two options?

Ok...don't have the statements, but the equations would be:
y=20+10X
y=50+5X

They would be equal in cost at X=6... For more than 6 days, the gym would be cheaper. For less than 6, the classes would be cheaper.

The true statement about the average cost for the two options is that:

the gym option costs less per class for six classes.
the gym option costs less per class for seven classes.

What are specified for the two options?

For high school classes, one-time fee of $20 plus $10 per class and for local gym, can join for $50 and take classes for $5 per class.

For 6 classes:

High school = $20 + $(10 + 10 + 10 + 10 + 10 + 10)

High school = $20 + $10 × 6 = $(20+60) = $80

Local gym = $50 + $(5+5+5+5+5+5)

Local gym = $20 + $5 × 6 = $(20+30)

Local gym = $50

For 7 classes:

High school = $20 + $(10 + 10 + 10 + 10 + 10 + 10 + 10)

High school = $20 + $10 × 7

High school = $(20+70)

High school = $90

Local gym = $50 + $(5+5+5+5+5+5+5)

Local gym = $20 + $5 × 7

Local gym = $(20+35)

Local gym = $55

Therefore, the Option B & D is correct.
