Answer:
30% and $30
Step-by-step explanation:
Well 240-168 is 72
72 is 30 percent of 240 because
240* x/100 = 72
24000x=7200
x=.3
.3 is percentage is 30%
We can check by doing
240*.3= 72
there is a 30% decrease
Next question
If the total price of something is 31.20 with a 4% tax we do
x * .04 + x = 31.20
because 4% added to the price of that object is 3.20
1.04x = 31.20
x= 30
we can check by doing
30*.04+ 30= 31.2
Answer:
The area is 8000 square feet.
Step-by-step explanation:
Since one inch in the drawing is equal to 20 feet, multiply 4 by 20 to get the length in feet. So the length equals 80 feet. Then multiply 5 by 20 to get the width. So the width equals 100. Finally plug the width and the length into the formula for Area. A= length X width; A= 80 X 100; A= 8000
So fill out the coordinate with those given numbers, and count how far apart they are and you will get your answer. Then times it by x.
