Answer:
Gradient of line A = 0.8
Gradient of line B = 0.75
Therefore the lines are not parallel
Step-by-step explanation:
1. Rearrange the equation of line A into the form Y=mX + C in order to find the gradient of line A which m in the equation represents the gradient.
2. Use the gradient formula, (y2-y1)/(x2-x1) to find the gradient of line B
Since the both have different gradient. It means that they are not parallel
£1 = 99.72 rupees -> £450 = 44874 rupees.
As the post office only has 500 rupee papers, once we calculate out the result, we have to round down to the nearest whole number.
The amount of rupee papers we can change out is : 44874 : 500 = 89.748 (papers)
We round down to 89 papers.
