$60 , because 20%=10%+10%, and 75 10%=7.5, 7.5+7.5=15, so 75-15=60
Answer:
The answer is Steps 1 and 2. Step 1: -3(x+2) = 5(x-7)
Step 2: -3x-6 = 5x-35
Step-by-step explanation:
Because <span>−8</span><span> does not contain the </span>variable<span> to solve for move it to the other side of the </span>equation<span> by adding </span>8<span> to both sides.
</span><span>5x=8+37
</span>Add 8<span> and </span>37<span> to get </span><span>45.
</span><span>5x=45
</span>Divide<span> each </span>term<span> by 5.
</span>x=<span>9
</span>
x is equal to 9

Answer:
Step-by-step explanation:
Let x represent the number of units of games sold.
The inventor of a new game believes that the variable cost for producing the game is $0.90 per unit and the fixed costs are $6200. It means that the total variable cost for x units would be
0.9 × x = 0.9x
The inventor sells each game for $1.69. This means that the total revenue from x units of games sold would be
1.69 × x = 1.69x
The total cost for a business is the sum of the variable cost and the fixed costs. Therefore, the total cost for the number of games sold would be
C = 6200 + 0.9x
Profit = Revenue - total cost
Therefore,
Profit = 1.69x - (6200 + 0.9x)
= 1.69x - 0.9x - 6200
= 0.79x - 6200
