Answer:

x=-5.25

Step-by-step explanation:

Original equation:

$2(3-x)-1.4(5-2x)=2x+5.3$

Distribute:

$6-2x-7+2.8x=2x+5.3$

Group like terms:

$(6-7)+(2.8x-2x)=2x+5.3$

Add like terms:

$-1+0.8x=2x+5.3$

Add 1 to both sides

$0.8x=2x+6.3$

Subtract 2x from both sides

$-1.2x=6.3$

Divide both sides by -1.2

$x=-5.25$

Silver scooter finds that it costs $300 to produce each scooter and the fixed costs are $750. The price is given by p=900-x, whe

Nady [450]

Cost = 300 x + 750 , where x is the number of the scooters;
Price = 900 - x
Profit = x ( 900 - x ) - ( 300 x + 750 ) =
= 900 x - x² - 300 x - 750 = - x² + 600 x - 750
d (Profit) = - 2 x + 600
- 2 x + 600 = 0
x = 600 : 2
x = 300
The company must produce 300 scooters to maximize the profit.
The maximum profit is:
- 300² + 600 · 300 - 750 = $89,250
