GUITAR Lydia wants to purchase guitar lessons. She sees a sign that gives the prices
for 7 guitar lessons and 11 guitar lessons.
Write a linear equation to find the total
cost for a lessons.

The total cost for the guitar lessons includes an initial cost fee which is

added to the unit cost.

Where the cost of 7 lessons is a and the cost of 11 lessons is b, we have

Where the cost for 7 lessons is $82, and the cost of 11 lessons is $122, we have;

Reasons:

The general equation for the total cost of lessons is;

Let a represent the cost of 7 guitar lessons, and let b represent the cost of

9 guitar lessons, given that the cost increases linearly with the number of

lessons, we have;

The cost increase per lesson = The slope of the linear function representing the total cost of a guitar lesson

Therefore;

Expressing the equation in the slope and intercept form, we have;

Where, in a similar question, a = $82, b = $122, we have;

y = 10·x + 12

The total cost of a lessons is; y = 10 × 1 + 12 = 22

The answer would be C=10d+12

Hope this helps
