Step-by-step explanation:
2(5x+7)+8x-7=27
We move all terms to the left:
2(5x+7)+8x-7-(27)=0
We add all the numbers together, and all the variables
8x+2(5x+7)-34=0
We multiply parentheses
8x+10x+14-34=0
We add all the numbers together, and all the variables
18x-20=0
We move all terms containing x to the left, all other terms to the right
18x=20
x=20/18
x=1+1/9
Answer:
$5,376
$47,376
Step-by-step explanation:
Given :
Price of current model = $42,000
Percentage increase in price = 12.8%
Price increase in dollars :
12.8% of $42000
0.128 * $42000
= $5,376
Price of the next model :
Price of current model + increase in price
$42000 + $5376
= $47,376
