Question

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.

Answer 1

Answer:

Cost of shoe must be less than or equal to $100

Step-by-step explanation:

Let the cost of the shoes he want to buy be $x$

Delivery Fee charged = one twentieth of cost of shoes

$DF=\frac{x}{20}$

Total Cost incurred = Cost + DF

= $x+\frac{x}{20}$

=$\frac{21x}{20}$

The budget of Albert is $105

Hence

$\frac{21x}{20}$≤105

21x≤2100

x≤$\frac{2100}{21}$

x≤100

Hence Albert must chose a shoe which costs him less than $100
