shelly made an $85-dollar profit on the halloween gram fundraiser. each gram sold for $2.

the cost of the materials totaled $23. how many grams were sold?

Step-by-step explanation:

If you add $23 and $85 together, it equals $108. That is final PRICE of grams sold but you are trying to find the total amount of GRAMS sold so you divide it by the cost of the grams which is $2 which equals, 54 grams were sold.

Full Explanation:

23+85=108

108/2 =54

well what did you do it matters what you did : )

step-by-step explanation:

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
