TechWiz Electronics makes a profit of $35 for each MP3 player sold and $18 for each DVD player sold. Last week, TechWiz sold a combined total of 133 MP3 and DVD players. Let x be the number of MP3 players TechWiz sold last week. Write an expression for the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.

Any ideas?

If x is the number of MP3 players and they have sold 133 in total how many DVD players have they sold?

OpenStudy (skullpatrol):

133 – x = number of DVD players

OpenStudy (skullpatrol):

Number of items • profit/item gives 35x + 18(133 – x) = total profit
