Printing a newsletter costs $1.50 per copy plus $450 in printers fees. the copies are sold for $3 each. how many copies of the newsletter must be sold to break even

300 copies of the newsletter must be sold to break even.

Step-by-step explanation:

Let there are k newspapers sold to break even.

Cost price of each paper = $1.50

So, the cost price of k newspapers =  k times $1.50  = 1.50 k

Printers fee  = $450

Now, total cost of printing k papers  = Printing Fee  + Cost price of k  papers

= $450 + $ 1.50k   =  450 + 1.50k

Selling price of each paper = $3

SO, the cost price of k newspapers =  k times $3  = 3 k

Now, to break even TOTAL COST = TOTAL SELLING PRICE

or, 450 + 1.50k = 3k

or, 450 =  3k - 1.50k

⇒ 1.5 k = 450

or,  k = 450 /1.5 = 300

⇒  k  = 300

Hence, 300 copies of the newsletter must be sold to break even.

1/3 + 1/5 = 8/15.
