The equation that models the scenario is y = 12.95 + 14.95x
<h3>How to determine the linear equation?</h3>
The given parameters are:
Ranch charge = $12.95
Entrance fee = $14.95 per house
Represent the number of houses with x, and the total charge with y
So, we have:
y = Ranch charge + Entrance fee * x
This gives
y = 12.95 + 14.95x
Hence, the equation that models the scenario is y = 12.95 + 14.95x

Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form use the method of completing the square
Given
x² - 8x + y² - 2y - 8 = 0 ( add 8 to both sides )
x² - 8x + y² - 2y = 8
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(- 4)x + 16 + y² + 2(- 1)y + 1 = 8 + 16 + 1
(x - 4)² + (y - 1)² = 25 → B
The amount of money Emma receives in this scenario is £35.
<h3>What is Ratio?</h3>
This is defined as a comparison of numbers that indicates their sizes in relation to each other.
Helen and Emma = 2 : 5
2 = 5
x = x+21
We then cross multiply
5x = 2 ( x+21)
5x = 2x + 42
5x - 2x = 42
3x = 42
x = 42/3 = 14
Emma received x+21
= 14+21 = £35
