Step-by-step explanation:

Set up the composite result function.

f(g(x))f(g(x))

Evaluate f(g(x))f(g(x)) by substituting in the value of gg into ff.

f(x2)=2(x2)−4f(x2)=2(x2)-4

Multiply 22 by x2x2.

f(x2)=2x2−4f(x2)=2x2-4

The price of a shirt is marked down from $12.50 to $10,00. What is the percent decrease of the shirt?

choli [55]

Answer: 20%.

Step-by-step explanation:

Given, The price of a shirt is marked down from $12.50 to $10.00.

Previous price = $12.50

New price = $10.00

Change in price = Previous price - New price

= $12.50 - $10.00

= $2.50

Now, the percent decrease of the shirt = $\dfrac{\text{Change in price}}{\text{Prevoius price}}\times100$

$=\dfrac{2.50}{12.50}\times100\\\\=20\%$

Hence, the percent decrease of the shirt = 20%.
