this is what i got but i still don't know that question.
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 [tex]x[/tex]
Delivery Fee charged = one twentieth of cost of shoes
[tex]DF=\frac{x}{20}[/tex]
Total Cost incurred = Cost + DF
= [tex]x+\frac{x}{20}[/tex]
=[tex]\frac{21x}{20}[/tex]
The budget of Albert is $105
Hence
[tex]\frac{21x}{20}[/tex]≤105
21x≤2100
x≤[tex]\frac{2100}{21}[/tex]
x≤100
Hence Albert must chose a shoe which costs him less than $100
