Step-by-step explanation:
You take 80-30 and are left with 50 so you divide that by 25 and get 2
increase price: $7,888
price of next model:65,888
Answer: 0.6 in 10 % ; 0.4 in 15 %
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
X= (39 * 100)/84
X= 46.42
