Algebra Word Problem.

Stumped on this question. One of the last questions in the section I'm working in. Thanks for the help.

During a recent sale, BMG Music Service charged \$8.49 for the first CD ordered and \$3.99 for all others. For shipping and handling, BMG charged \$2.47 for the first CD, \$2.28 for the second CD, and \$1.99 for all others. The total cost of a shipment (excluding tax) was \$65.07. How many CD's were in the shipment?

x = total number of cd's ordered

$[8.49+3.99(x-1)] + [2.47+2.28+1.99(x-2)] = 65.07$

solve for x

Hey, where ya been Mike?

n = number of CD's - 1

8.49 + 3.99n + 2.47 + 1.99n + .29 = 65.07
(the .29 is to adjust for shipping/handling of 2nd CD : 2.28 - 1.99)

Solve for n.

Cute problem!
Thanks from Mike462

The given figures mean that 10 CDs would give rise to a total cost (before tax) of \$65.07. I got this answer the quick way.

It's more fun to play snooker than watch it, imho, but sometimes the professional games can be real nail biters to watch.... the slow pace, the silence during the shots, the massive difficulty associated with the highly precise shots and the fact that one mistake can cost you the whole frame sometimes makes for a really, really tense and exciting atmosphere.

Cricket however... get the beers out!
