#12: Kara is deciding between The Lyme Point Inn and Ever After Farms for 1 point her wedding reception. The Lyme Point Inn charges $3,000 for the venue

and $100 for each meal. Ever After Farm charges $5,400 for the venue and

$70 for each meal. Write and solve an equation to find the number of

meals at which the total cost charged by the two venues would be the

same. *

Your answer

ooo

80 meals

Step-by-step explanation:

Set up an equation where x is the number of meals:

100x + 3000 = 70x + 5400

Solve for x:

100x + 3000 = 70x + 5400

30x + 3000 = 5400

30x = 2400

x = 80

So, at 80 meals, the cost of the 2 venues will be the same

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
