Question

if each mp3 player is $35 and dvds players are $18 the combined total is 132 what an expression for the combined total profit

Answer 1

35x+18x=132

Explanation:

we don’t know the number of mp3 of dvd players so we have to use x. Since $35 is for the mp3 players each and $18 for dvd players each, they have to equal up to 132. Making the equation 35x+18x=132
