In a the department store a $50 dresses is Marked save 25% what is the discount what sale price of the dress
NemiM [27]

Answer:

Discount of $12.50.

Sale price is $37.50.

Step-by-step explanation:

Since the dress is "Marked save 25%" this means yuo pay 75% of the $50 price. Remember, 100-25 = 75. This means you pay 0.75*50 = $37.50 and yuo got a discount of $12.50.

$50 - 37.50 = 12.50

What is the multiplicative rate of change of the exponential function shown on the graph? 1 4
marta [7]
The answer:
the main formula for computing the multiplicative rate of change is given by:

Mutiplicative Rate of Change = [f(x2)/f(x1)]  / (x2 -x1)
this formula can be written as
 [f(x2)/f(x1)]  / (x2 -x1) = [f(x2) * (x2 -x1) /f(x1)] 

for example we can take (x1, f(x1))= (0, 2) and (x2, f(x2))= (1, 5) 
therefore,
Mutiplicative Rate of Change = [5/2]  / (1-0)= 5/2= 2.5

the answer is 2.5
