There are 20 guest at a paris. the host has 8 gallons of punch. he estimates at each guest will drink 2 cups of punch. if his estimate is correct, how much punch will be left over at the end of the party?

i dont know i just need points

include a picture of the drawing in order for me to

step-by-step explanation:

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

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
