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.

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

Delivery Fee charged = one twentieth of cost of shoes

Total Cost incurred = Cost + DF

=

=

The budget of Albert is $105

Hence

≤105

21x≤2100

x≤

x≤100

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

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
