Answer:

(n/4) - 5  =  2(n-14)

Step-by-step explanation:

let the number be n

"25% of n" : (25/100)n = n/4

"Five less than 25% of n" : (n/4) - 5  

"difference between the number and 14" : n - 14

" twice the difference between the number and 14" : 2(n-14)

Assembling all the parts:

(n/4) - 5  =  2(n-14)

If Fun Reads Bookstore has a ready club with a $40 fee and charges $5 per book and Cool Covers Bookstores club charges $100 fee
choli [55]

Answer:

You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.

Step-by-step explanation:

Given that:

Fee charged by Fun Reads Bookstore = $40

Charges per book = $5

Let x be the number of books.

A(x) = 5x+40

Fee charged by Cool Covers Bookstore = $100

Charges per book = $2

B(x) = 2x+100

For making Cool Cover Bookstores club a better deal,

B(x) > A(x)

2x+100 > 5x+40

2x-5x > 40-100

-3x > -60

Dividing both sides by -3

\frac{-3x}{-3}>\frac{-60}{-3}\\x>20

Hence,

You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.
