Mathematics

Answer:

x = 7

Step-by-step explanation:

We can solve the equation 5x+3+8x-4=90 by isolating the variable x on one side. To do this, we must simplify the equation.

5x+3+8x-4=90

Combine like terms:

13x - 1 = 90

Add 1 to both sides:

13x = 91

Divide both sides by 13:

x = 7

Hope this helped!

Answer:

x = 7

Step-by-step exxplanation:

5x + 3 + 8x - 4 = 90

5x + 8x = 90 - 3 + 4

13x = 91

x = 91/13

x = 7

probe:

5*7 + 3 + 8*7 - 4 = 90

35 + 3 + 56 - 4 = 90

Suppose you invest $10,400 in equipment to manufacture a new board game. Each game costs $2.65 to manufacture and sells for $20.
tamaranim1 [39]
Answer: 599.42 games
To answer this question, you need to calculate the revenue for every game sold first. The calculation would be:
Revenue= sell cost - manufacture cost= $20-$2.65= $17.35/game.

Break even is the point when the game manufacturing cost(equipment cost included) is covered by the revenue you got. Then the calculation would be:

total game cost= revenue per game * number of game sold
$10400= number of game sold * $17.35
number of game sold= 10400/17.35=  599.42 games
