The problem below has been solved incorrectly. Find and identify the error. Then, determine the correct answer and show/explain how you found it:
Gaming systems are on sale for 25% off the original price (s) which can be expressed with the function p(g) = 0.75g. Local taxes are an
additional 9% of the discounted price (p), which can be expressed with the function cp) = 1.09p. Using this information, write an expression
that represents the final price of a gaming system with the discount and taxes applied. Explain how you came up with the expression

Incorrect answer:
g = original price
p(g) = 0.75g = discounted price
1.09p = tax
total cost = 0.75g +1.09p
To find the total cost you would have to add the discount price and tax together. ​
