Last month Bob's bill was $80.77. This month Bob's bill was $69.06. What is the percent decrease?
80.77-69.06=11.71
11.71 divide 80.77
Round answer
Answer: 0.14
Is 0.14 the correct answer?
No.
How do I solve this?
You didn't go far enough. You forgot to multiply your decimal answer by 100 to get the percentage.
0.1449 = 14.49%
To calculate the percent decrease, you need to find the difference between the two values and then divide it by the original value. Let's break down the steps:
1. Find the difference between the two values:
$80.77 - $69.06 = $11.71
2. Divide the difference by the original value:
$11.71 / $80.77 = 0.145
3. Convert the decimal to a percentage by multiplying by 100:
0.145 * 100 = 14.5%
So, the correct answer is 14.5%. Therefore, 0.14 is not the correct answer; it should be 14.5%.
