Bryan has to take 8 classes for both Pro's to be the same price.
Step-by-step explanation:
Given,
Monthly charges of Pro at Windy = $20.00
Charges per lesson = $10.00
Let,
x be the number of lessons
W(x) = 10x +20
Monthly charges of Sunny Sands = $100.00
They offer unlimited classes.
S(x) = 100
For the price to be same;
W(x) = S(x)
[tex]10x+20=100\\10x=100-20\\10x=80[/tex]
Dividing both sides by 10
[tex]\frac{10x}{10}=\frac{80}{10}\\x=8[/tex]
