Each roll of tickets = 100 tickets
32 * 100 = 3200
3,200 tickets were ordered in all.
Answer:
--- equation
--- value at 5th year
Step-by-step explanation:
Given
decrease
Required
Determine the linear equation
Determine the value at the 5th year
Represent years with x.
If the rate in 1 year is 2200,
in x years, it'll be 2200x (decrement)
So, the value (y) at x years is.
The value at the 5th year is when x = 5.
So, we have:
Answer:
First number (x) = 12
Second number (y) = 80
Third number (z) = 20
Step-by-step explanation:
Let assume x,y,z to represent first, second and third respectively.
X + y + z = 112
Y = 4z
X = z - 8
So therefore
(Z-8) + (4z) + z = 112
Z + 4z + z = 112 + 8
6z = 120
Z = 120/6
Z = 20.
So,
First x = z - 8
20 - 8 = 12
Second y = 4z
4 x 20 = 80
Third z = 20
