We can use two different ways to solve this equation:
Because the board is 25 off, we can multiply the price and subtract the result:
30 - 0.25(30) = 30 - 7.5 = $22.50
We can also solve by multiplying the total price by 0.75
(1 - 0.25)(30) = 0.75(30) = $22.50
The sales price is $22.50
Answer: 300
You need to change 9% into a decimal so it would be 0.09
Then divide 27 ÷ 0.09 = 300
So 9% of 300 is 27
(17.5)(x)=125
Divide each side by 17.5 leaving the equation as x=7.14
Answer:
y=-75x+2400
Step-by-step explanation:
y is the height
-75 is the rate of change so you put that before your x
2400 is your starting value/y intercept
not very good explanation but hope this helps
