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? Last edited by skipjack; January 8th, 2019 at 10:10 AM.

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

Cute problem! Thanks from Mike462

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!
