Sarah was locked out of her apartment and the only way out is through a window three stories high 20 feet above the ground. She needed to borrow from one of her friends. There is a tree along the side of the house so she will need to put the ladder 15 feet from her apartment. How long does the ladder need to be to reach the apartment window?
Answer:
$34.20
Step-by-step explanation:
First, find the cost with tax
You are paying 7.2% tax, but you are also paying for 100% of the bill
100%+7.2%=107.2%
So, you are really paying for 107.2% of the bill
Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right
107.2/100=1.072
Multiply the decimal by the cost of the bill
1.072*45.90=49.2048
But, we also have a coupon for $15 off
Subtract 15 from the cost with tax
49.2048-15=34.2048
Round to the nearest cent/hundreth
$34.20
Hope this helps! :)
