Edwin's graph
y = 7 when x = 2.
Sam's equation
P = 3.4g
Edwin:
y = kx
k = y/x = 7/2 = 3.5 cost per gallon
y = 3.5x
Sam's equation:
P = 3.4g
y = 3.4x
Sam buys milk at a lower rate for the price of 3.4 per gallon.
Edwin buys milk at 3.5 per gallon
Answer:
<em><u>The number of students that like only Nokia </u></em>
<h2>= 30</h2>
Step-by-step explanation:
consider N the number of students who like Nokia → N=?
T the number of students who like Techno → T=35
Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno
we can translate it like this: 35 student like Nokia or Techno
we can note it like this : T∪N= 35
Statement 2: 30 like Techno and Nokia
we can note it : T∩N = 30
using a rule concerning the number of element of a set :
T∪N = N + T - T∩N
then
35 = N + 35 - 30
⇒ N - 30 = 0
⇒ N = 30
