Answer:
[tex]8x+15[/tex]≤[tex]65[/tex]
[tex]x=\frac{25}{4}[/tex]
Step-by-step explanation:
let the number of books purchased = x
cost of each book = $8
Cost incurred on books = 8x
money to be saved for miscellaneous expenses= $15
Total cost = 8x+15
We are given that total cost need to be less than or equal to $65
Hence
8x+15≤65
subtracting 15 from both sides
8x≤50
diving both sides by 8
[tex]\frac{8x}{8}=\frac{50}{8}[/tex]
[tex]x=\frac{25}{4}[/tex]
