Answer:
(5 , 0)
Step-by-step explanation:
7 * (−9y+4x−20)=0
9 * (−7y+16x−80)=0
-63y + 28x -140 = 0 ......a
-63y + 144x -720 = 0 .....b
b-a: 116x - 580 = 0
116x = 580
x = 5
y = (4x-20)/-9 = 0/-9 = 0
Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28
Answer:
Option A.
Step-by-step explanation:
Let M be the milk per gallon.
C be the cookies per dozen.
B be the bundle (one gallon of milk and a dozen cookies ).
Milk can be sold by itself for a profit of $1.50 per gallon. Cookies can likewise be sold at a profit of $2.50 per dozen and bundle is sold for a profit of $3.00 per bundle.
We need to maximize the profits. So, our objective function is
Therefore, the correct option is A.
