Answer:
2
1/3
Step-by-step explanation:
A(xA, yA) = A (3,1)
B(xB,yB)=B(5,5)
the gradient=(yB-yA)/ (xB-xA)=(5-1)/(5-3)=4/2=2
C(4,7),D(10,9)
the gradient=(yD-yC)/(xD-xC)=(9-7)/(10-4)=2/6=1/3
Answer:

Step-by-step explanation:
Given: Marisa bought four bottles
Price of each bottle is $0.95.
Solving with the factors as given to find the total cost paid by Marisa.
Total cost= 
∴ Total cost paid by Marisa is $3.8.
As given to write an equation with the same product as the total cost but different factors.
∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"
We already find the total cost she paid is $3.8.
Now, writing an equation with different factors, as total cost remain same.

Dividing both side by 5
we get x= $ 0.76
∴ The required equation is
