Jason purchased a pack of game cards that was on sale for 13% off. The sales tax in his county is 8%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.

0.9396y

Step-by-step explanation:

sale = 13% of original price = 13% of y

13% = 0.13 by dividing by 100 to convert it to a decimal

13% of y = 0.13y

new amount = original amount - sale = 1y - 0.13y = 0.87y

tax = 8% of new price = 0.08 * (0.87)y

final amount = new amount + taxed amount = 0.87y + 0.08*(0.87)y = (0.87 + 0.08 * 0.87)y = 0.9396y

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
