Section 1.2: Applied Percentage Problems

Question

Question 33:

A company wants to decrease its energy use by 15%.

(a) If their electric bill is currently $2,037 a month, what will their bill be if they're successful?

$

(b) If their next bill is $2,000 a month, were they successful? What percent decrease was there from the current bill?

1. Yes
2. No

% (Give your answer to two decimal places)

Answer 1

2037 - 15% =

.85(2037) = $1,731.45 after a 15% decrease

a bill of $2000 is not a success.

x(2037) = 2000

x =2000/2037 = 98.18% = 1.81% decrease < 15%
