calculate the percent change in the water bill from august to september. round to the nearest whole percent.\n| expense | august | september |\n| ---- | ---- | ---- |\n| electricity | $100.00 | $120.00 |\n| water | $48.00 | $36.00 |\n| groceries | $150.00 | $165.00 |\n| restaurant | $80.00 | $96.00 |
Answer
Answer:
25% decrease
Explanation:
Step1: Identify old and new values
Old value (August water bill) = $48.00, New value (September water bill) = $36.00
Step2: Calculate change amount
Change amount=$48 - 36=12$
Step3: Calculate percent - change
Percent change = $\frac{\text{Change amount}}{\text{Old value}}\times100=\frac{12}{48}\times 100 = 25$ Since the new value is less than the old value, it is a 25% decrease.
