When we are looking at Class 1. There is a $20 sign up fee which we will have to add to our total. If it is $20 per lesson and we are finding the better price for 10 lessons, we can take the $20 and multiply it by the 10 lessons she wants to take. Which would give us $200. Add on the $20 signup fee and the total becomes $220 for Class 1.
When it comes to Class 2, we have a steeper sign up fee of $40, however it is $12 per lesson. We simply do the exact same thing as we did in Class 1, where we take $12 and multiply it by the 10 lessons to get $120 and then add on the signup fee which would total up to $160.
So in the end, Class 2 would be the better price for 10 lessons as the total cost of it would only be $160, compared to the Class 1 total price which is $220.
