Answer:
The weight increase by 12 and the dosage increase by 2.5
Step-by-step explanation:
5.5x + 3 = y
7x =y
5.5x + 3 = 7x (-5.5x both sides)
3 = 1.5x (÷1.5 both sides)
X = 2

Answer:
x=400 and y=800
Step-by-step explanation:
let x be the Quartez and y is Pacer
x+y≤1200 ( maximum production capacity of 1200 cars per week)
0≤x≤600
0≤y≤800
profit : 500x+800y
at a point : x=0 y=800
profit=500x+800y ⇒ 500(0)+800(800)=640000
profit= 500(600)+0=300000 wen x=600(max), y=0
Profit=500(600)+800(600)= 780000
profit =500(400)+800(800)=840000 this is the max profit when
x=400 and y=800
