Question

TechWiz Electronics makes a profit of $35 for each MP3 or player sold and $18 for each DVD player sold. Last week, TechWiz sold a combined total of 118 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.

Answer 1

Answer: 118=x+y z=35x+18y

Step-by-step explanation: x= the amount of MP3 players, and y= DVD Players. The 35 and 18 represent the profit for both of them, and in the first equation, the 118 shows the total amount sold. The z represents the profit made, because you are multiplying the amount of MP3 players and DVD players by their price, then adding them for the total amount.
