We can generalise this by finding the equation of the line.
The gradient is: 15
We can take when x = 10, and y = 150 to find the equation of the line.
y - 150 = 15(x - 10)
y - 150 = 15x - 150
y = 15x
Thus, when x = 80, y = $1200 (ie B)

Answer:
0.0560042
Step-by-step explanation:
First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:

Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:

Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:

Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.
We can conclude that <span>
Marguerite will need 4 boards of wood.</span>
