Answer

Explanation:

Step1: Determine number of DVD players

If $x$ is the number of MP3 players sold and the total number of MP3 and DVD players sold is 139, then the number of DVD players sold is $139 - x$.

Step2: Calculate profit from MP3 players

The profit from selling MP3 players is $35x$ (since profit per MP3 player is $35$).

Step3: Calculate profit from DVD players

The profit from selling DVD players is $18(139 - x)$ (since profit per DVD player is $18$).

Step4: Find combined profit

The combined total profit $P$ is the sum of the profit from MP3 players and DVD players. So $P=35x + 18(139 - x)$. Expand the second - term: $P = 35x+18\times139-18x$. Combine like terms: $P=(35x - 18x)+18\times139$. $P = 17x+2502$.

Answer:

$17x + 2502$
