Question

Type the correct answer in each box. Use numerals instead of words.
Albert has $105 to spend on new basketball shoes. On his favorite shoe website, the prices for a pair of the shoes range from $80 to $180. The delivery fee is one-twentieth of the price of the basketball shoes. The total cost can be modeled by the function, f(c), where c represents the price of the basketball shoes.
The domain of the function is [
,
].

Before purchasing the shoes, Albert remembered that his friend had to repay him an amount of money of $42. After receiving this amount, the domain for the function to represent the price of the basketball shoes that Albert can afford is [
,
].

Answer 1

Answer:

Step-by-step explanation:

Given that prices for a pair of shoes lie in the interval

[80,180] dollars.

Delivery fee 20% of price.  

i.e. delivery fee will be in the interval [4, 9]

(1/20th of price)

Total cost= price of shoedelivery cost

Hence f(c) = c+c/20 = 21c/20

The domain of this function would be c lying between 80 to 180

So domain =[80,180]

---------------------------------

Amount to be repaid = 42 dollars

Once he received this amount, the price would be

105+42 =147

But since price range is only [21*80/20, 21*180/20]

=[84, 189]

Since now Albert has 147 dollars, he can afford is

[80,147]
