Your standard equation is y = mx + b
P should be the output (y) because it is the final bill. B should be represented by 200 because the $200 is an additional, once payed fee. M should be 30 because the amount payed for dinner depends on how many people are served.
p = final bill
b = 200
m = 30
x = number of friends
So, your equation would look like p = 30x + 200
Hope this helps!
Answer:
1.98 pounds
Step-by-step explanation:
One week = 7 days
Set up a ratio.
8.5/30 = x/7
x = 7(8.5)/30 = 1.98 pounds.
Sub in what X and y are:

. Solve the exponents (if the exponent is 2 multiply the whole number by itself twice, if it were 3 you would multiply the whole number by itself three times): 3·3=9, 3·3=9: 9(9)= 81. :)
<h2>
There are 120 pine trees and 180 maple trees.</h2>
Step-by-step explanation:
Total number of trees = 300
Given that for every two pine trees there will be 3 maple trees.
Let 2t be the total number of pine trees.
Then total number of maple trees is 3t.
Total number of trees = 2 t + 3 t = 5 t
That is
5t = 300
t = 60
Total number of pine trees = 2t = 2 x 60 = 120
Total number of maple trees = 3t = 3 x 60 = 180
There are 120 pine trees and 180 maple trees.
C! All you have to do is substitute the numbers into the problem!
