The right answer is Option C: 20
Step-by-step explanation:
Given,
Cost of medium cup of coffee = $3.00
Cost of large cup of coffee = $4.00
Total cups sold = 35
Total revenue for the coffee = $125.00
Let,
Number of medium cups of coffee = x
Number of large cups of coffee = y
According to given statement;
x+y=35 Eqn 1
3.00x+4.00y=125.00 Eqn 2
Multiplying Eqn 1 by 3;

Subtracting Eqn 3 from Eqn 2

As y represents the number of large cups, therefore,
20 large cups of coffee were sold by the shop.

We are given
are odd which means:


We can tell if a function,
, is even if
.
We can tell if a function,
, is odd if
.
So let's test your I,II,III.
We will be replacing x with -x to find out.
I.





So
is odd.
II






So
is odd.
III





So
is even.
So I and II are odd and III is even.
C. is the answer.
