Answer:

When x=0, y=4...

Therefore:

4=a*b⁰

b⁰=1, so a=4.

----------

When x=1, y=2...

Therefore:

2=4*b¹

4b=2

b=2/4

So... b=1/2.

This means that:

y=4*((1/2)^x)

Please help me this is very important
Virty [35]

Answer:

a. 24.5 $

b. 10.5 $

c. 7/10

Step-by-step explanation:

Given the original price of the sweater is: $ 35.

a) If you pay only $ \frac{7}{10} $ of the price, then the actual amount paid is: $ \frac{7}{10} \times 35 = \frac{49}{2} $ = 24.5 $.

b) Total amount Saved = Actual price - Price you paid

$ \implies $ Total Amount Saved = $ 35 - \frac{49}{2} $

$ = \frac{21}{2} $ = 10.5 $.

c) Fraction of the original price saved = Total amount Spent/Actual Price

$ \implies $ Total amount Saved = $ \frac{49}{2(35)} $

$ = \frac{49}{70} $ = $ \frac{7}{10} $
