Answer:
A = 1.5x + 1400
Step-by-step explanation:
Let us represent
The number of Adults = x
The number is children = y
The total amount of money raised = A
We are told in the question that:
A pancake breakfast fundraiser served 400 people and charged $5 for adults and $3.50 for children.
Hence:
x + y = 400.... Equation 1
y = 400 - x
Hence:
A = $5 × x + $3.50 × y
A = 5x + 3.50y
Where y = 400 - x
A = 5x + 3.50(400 - x)
A = 5x + 1400 - 3.50x
A = 1.5x + 1400
The equation for how much money was raised is given as:
A = 1.5x + 1400
Step-by-step explanation:
f(x) = y ( true statement)
y = -1/5x + 3
To find the inverse of any given function we switch the X and Y
X = -1/5y + 3
isolate y so:
x-3 = -1/5y
Multiply both sides by -5
-5(x-3) = y
-5x + 15 = y
