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.
So first you find out how much money he makes per week, by doing 7.5 x 20 you will find that. Now you need to find how many weeks it will take, find this by dividing 1200 by the amount he makes per week and you will end up with 8.
