1 point A farmer finds that if she plants 95 trees per acre, each tree will yield 55
bushels of fruit. She estimates that for each additional tree planted per
acre, the yield of each tree will decrease by 3 bushels. How many trees per
acre should she plant to maximize her harvest? *

this doesn't make sense lol

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
