Faith owns an organic apple orchard. From her experience the last few seasons, she has developed the formula P=20x-0.01x^2 -240 to predict her profit P in dollars this season if her trees produce x bushels of apples. What is Faith’s predicted profit this season if her orchard produces 300 bushels of apples?

Ответ:
P=20x-0.01x^2-240
P=20(300)-0.01(300)^2-240
P=6000-0.01(90000)-240
P=6000-900-240
P=4860
Remember PEMDAS
Parentheses
Exponents

Subtraction
EXPLANATION: first Is Parentheses, which would be 300, multiply that by 20, that would be 6000.
Next is Exponents, which would be the (^2) so you would Multiply the 300 by itself 2 times. which is 90000
Next is Multiplication, Multiply 0.01 by 90000, which would be 900.
There is nothing to divide or add so skip that.
Next is subtraction, subtract 6000-900-240 and the answer would be 4860.
so Faith's prediction profit for this season would be 4860 when her orchard produces 300 bushels of apples.
I hope that helped! Good Luck!
