45 min = 3/4 hour
55 dollars per 4*3 sessions
=55/12 per session
=(55/12)*(4/3) per hour
=55/9 =6.1

Total number of minutes = \(45\)(minutes per session)*\(3\)(times a week)*\(4\)(no.of weeks) = 540
Total number of hours \(= \frac{540}{60} = 9\) hours
Per hour charge \(= \frac{55}{90} = 6.1\)

Hence C, \($6.1\)

My Solution:

$55= number of classes
$55= 4(3)
$55=12
12 classes =12 hours

BUT 12(.75)=9 hours since a class only last 3/4 of an hour
55/9= $6.1 per class

The total charge for a 4-week dance class is $55.00. The class has 3 sessions per week, and each session lasts 45 minutes. Approximately what is the charge per hour for the class?

A. $18.30
B. $13.75
C. $6.10
D. $5.35
E. $4.60



using the information we can say :

(55*60/( 4*3*45)
= $6.10 option C
