9.8 percent decrease
Step-by-step explanation:
To find the percent decrease, we take the original value and subtract the new value and divide by the original value.
percent decrease = (original - new)/ original
= (23.5 - 21.2)/ 23.5
=2.3/23.5
=.09787234
This is in decimal form. Multiply by 100 to put it in percent form
9.787234 percent
Round to the nearest tenth so we look at the 8 and round up.
9.8 percent decrease
Answer:
4.2 miles (Answer b)

1 yard 5280 ft
350 + 4x = 750
x = the amount the fee went up annually.
4x = 750 - 350
4x = 400
x = 400/4
x = 100
The rate of change is 100 dollars per year. The initial value of her business is 350 dollars. To check your work (aka how do you know) if you add 100 dollars to her initial value (350) 4 times you get 750.
X=-8.5
u would solve by isolating x
