Answer:
The installation fee is $150
Step-by-step explanation:
Ok so we need to see how much of the $210 is the installation fee. So first were going to multiply 5 by 12 which equals 60. So now were going to subtract that from the $210 so that gives us...
$210-$60=$150
Answer:
Step-by-step explanation:
(1+25 /100) (1-20/100) (1-50/100) <1
5/4 x 4/5 x 1/2 <1
Decrease in volume (in percent)
(1+25 /100) (1-20/100) (1-50/100) x 100
=48.8%
X ÷ 2 - 13 = 1
Write the division as a fraction

Multiple both sides of the equation by 2

Reduce the number with greatest common divisor 2

Multiply the numbers

Then u will have

Move constant to the right by adding its opposite sides

Eliminate the opposites

Then you have

Add the numbers
With adding and subtracting fractions, you must find a common denominator. In multiplication, you just multiply numerator by numerator; denominator by denominator. In division, you multiply the fraction by the reciprocal of the 2nd. In multiplication and division, finding a common denominator is not needed.
