Final answer:
To find the percentage decrease in Bong's savings from February to May, subtract the later savings from the earlier, then divide by the earlier savings and multiply by 100. Bong's savings decreased by ₱2,200, resulting in a percentage decrease of 23.15%.
Step-by-step explanation:
To calculate the percentage decrease in Bong's savings from February to May, we start by finding the difference in savings between these two months. We subtract the May savings (₱7,300) from the February savings (₱9,500), which gives us ₱(9,500 - 7,300) = ₱2,200. This is the decrease in savings.
To find the percentage decrease, we divide the decrease by the original amount (February savings) and multiply by 100 to get the percentage. The formula is as follows:
Percentage Decrease = (change in savings)/(original savings) × 100
Percentage Decrease = (₱2,200)/(₱9,500) × 100
Percentage Decrease = 0.2315 × 100
Percentage Decrease = 23.15%
Therefore, the percentage decrease in Bong's savings from February to May was 23.15%.
