Answer: 98
Step-by-step explanation: 180 - 82 = 98
180 - 80 = 100, and 100 - 2 is 98.
Answer:
Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so
An aircraft has a maximum of 220 economy seats
A flight will be cancelled if the money taken for the seats is less than $28,800.
so
therefore
Three inequalities that represent the situation are
I'm assuming the function is f(x) = 100(0.7)^x. This is the same as y = 100(0.7)^x because y = f(x).
Plug in x = 0 to get
y = 100(0.7)^x
y = 100(0.7)^0
y = 100(1)
y = 100
So (x,y) = (0,100) is one point on this function curve
Plug in x = 2 to get
y = 100(0.7)^x
y = 100(0.7)^2
y = 100(0.49)
y = 49
So (x,y) = (2,49) is another point on this curve
In summary, the two points on this function curve are (0,100) and (2,49)
