Calculating the cost of 4.25 kilogram(kg) is £2.38, by multiplying it by 4.25 kg by 1 kg.
<h3>Cost</h3>
Costs are the expenses incurred in the manufacture, marketing, or preparation of a good or asset for regular use. In other terms, it's the cost incurred to produce a good, buy inventories, sell goods, or prepare equipment for use in a commercial activity.
Given,
2.5 kg cost £1.40 i.e,
2.5 kg = £1.40
For 1 kg= 
= £0.56
To find the cost of 4.25 kg:
Then,
1 kg = £0.56
4.25 kg = 0.56 x 4.25
= £2.38
£2.38 is the cost of 4.25kg after calculating it.

Answer:
2.42
Step-by-step explanation:
First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.
Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.
Y1-15.54=10.36x -15.54 get y1 by itself
Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42
A. X is a variable, not a number on the coordinate plane.
This math is just too much and makes little to no sense.
Answer:
No, the expression is not linear because the highest power of x is 2.
