Explanation:
(a) To calculate the reduction as a percentage of the marked price, we can use the formula:
Reduction Percentage = (Reduction / Marked Price) * 100
Given:
Marked Price = $640
Reduction = $640 - $560 = $80
Substituting these values into the formula:
Reduction Percentage = ($80 / $640) * 100
Reduction Percentage ≈ 12.5%
Therefore, the reduction as a percentage of the marked price is approximately 12.5%.
(b) To find the amount the shop paid for the chromebook, we can use the information that $560 is 25% more than the amount the shop paid.
Let's assume the amount the shop paid is X dollars.
25% more than X can be calculated as:
X + (25/100) * X = X + 0.25X = 1.25X
Given:
$560 = 1.25X
To find X, we can divide both sides of the equation by 1.25:
X = $560 / 1.25
X = $448
Therefore, the shop paid $448 for the chromebook.
