Answer:
He should sell his CD's for $2.
Step-by-step explanation:
Each crate contains 60 blank CD’s and each crate cost $35.
This means that he will pay $35 for 60 CD's.
How much should he sell his CD’s to make a profit of $85?
He will sell each of the 60 CD's for x, which means that his earnings will be of 60x.
Profit: Earnings - Cost = 60x - 35
To make a profit of $85
He should sell his CD's for $2.
Answer:
4/7 =x
Step-by-step explanation:
6 - 2/3(x+5)=4x
Multiply each side by 3 to clear the fraction
3(6 - 2/3(x+5))=4x*3
Distribute
18 -2(x+5) =12x
Distribute the 2
18 -2x-10 = 12x
Combine like terms
8 -2x = 12x
Add 2x to each side
8-2x+2x =12x+2x
8 = 14x
Divide by 14 on each side
8/14 =14x/14
4/7 =x
