The unit rate of the cost of different weight of pistachios as shown on the graph is $1.25 per pounds.
<h3>What is unit rate?</h3>
A unit rate is a rate where the second quantity is one unit . Therefore, the unit rate of the linear graph can be found as follows;
(2, 2.5)(4, 5)
unit rate = y₂ - y₁ / x₂ - x₁
x₁ = 2
x₂ = 4
y₁ = 2.5
y₂ = 5
unit rate = 5 - 2.5 / 4 - 2 = 2.5 / 2 = $1.25 per pounds

Let x represent some number
Sum of 3 and twice some number = 3 +2x
Five times the sum of 3 and twice some number: 5(3+2x)
5(3+2x)=70
15+10x=70
Subtract 15 from both sides to have 10x by itself
10x=55
Divide 10 on both sides to get x by itself
x=55/10
x=5.5
Hope this helped
