Answer (3)
The question is asking how to calculate the percentage increase in the cost of a bag of fertilizer, which is a common application of percentage change in mathematics. To find the percentage increase, you will need to know the change in the cost and the original cost, then use the formula:
Percentage Change = (Change in quantity / Original quantity) × 100
The change in the cost of the fertilizer is $15 - $8 = $7. The original cost is $8. Using our formula:
Percentage Change = ($7 / $8) × 100 = 0.875 × 100 = 87.5%
Therefore, the cost increase can be represented as a fraction (7/8), a percentage (87.5%), and a decimal (0.875).
price of a bag of fertilizer increased from $8 t0 $15 thus the price increase = $7 % increase = 7/8 * 100 = 87.5% in decimal = 0.875 divide by 100 in fraction = 875/1000
The percentage increase in the cost of fertilizer from $8 to $15 is 87.5%. This can be represented as a fraction 8 7 and as a decimal 0.875. This calculation shows how the price change can significantly impact costs in a business.
