Step-by-step explanation:
Here,
x= elapsed time
y = number of gallons of water in tank.
For tank A,
3y=750x+300
Divide both sides by 3, we get
y= 250x+100 ...(i)
For tank B,
4y=1000x+400
Divide both sides by 4, we get
y=250+100 ...(ii)
From (i) and (ii) it can be seen that both the function are same.
That means the amount of watre will be same for every value of x, where x ≥0
Cost of two tickets that Sheila paid to her friend = $ 90
Actual price of 1 ticket = $ 52.50
So, actual price of 2 tickets = 52 x 2 = 105
Hence, markdown or discount Sheila's friend gave her is =
105 - 90 = 15
The answer is $15.
5x+2y=12 5x+2y=12
5x-2y=28 5(4)+2y=12
2y=12-20
10x=40 2y=-8
x=40/10 y=-8/2
x=4 y=-4
