Using this conversion graph, work out the value that completes the formula. cost = Cost against mass of oranges Cost (£) 40 35 30 25 x mass of oranges 20 15 10- 0 5 10 15 20 Mass of oranges (kg)
Answer :
The complete formula is:
Cost = 3 x mass of oranges
To determine the value that completes the formula "Cost = ____ x mass of oranges," we can use the information provided by the conversion graph, which relates the cost to the mass of oranges. The graph passes through two points: (0, 0) and (10, 30).
The formula you are looking for can be represented as:
Cost = (slope) x mass of oranges
To find the slope, we can use the formula:
Slope = (change in y) / (change in x)
In this case, the change in y is 30 (the cost increases by 30), and the change in x is 10 (the mass of oranges increases by 10). So, the slope is:
Slope = 30 / 10
= 3
Now that we have the slope, we can complete the formula:
Cost = 3 x mass of oranges
So, the value that completes the formula is 3. Therefore, the complete formula is:
Cost = 3 x mass of oranges
