The store offers a 5% discount for every 50th customer who makes a purchase. If Cindy gets the 5% discount, which expression will represent Cindy’s bill?

Verified Answer :

Answer:

\(0.95(1.09m+2.79n)\)

Step-by-step explanation:

A store sells 12-packs of ballpoint pens for $1.09 each.

The store also sells composition books for $2.79 each.

Cindy buys 'm' packs of ballpoint pens and 'n' composition books.

So, the equation for this becomes:

\(1.09m+2.79n\)

And as Cindy gets a 5% discount, so she has to pay 95% of the regular price.

Then the expression that will represent Cindy’s bill is :

\(0.95(1.09m+2.79n)\)
