The linear equation that best fits the data is: y = 10x + 15.
<h3>How to Write the Linear Equation of a Data?</h3>
First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.
Using two points on the graph, (1, 25) and (2, 35), find the slope (m):
Slope (m) = (35 - 25)/(2 - 1)
Slope (m) = 10/1
Slope (m) = 10
Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b
25 = 10(1) + b
25 - 10 = b
b = 15
Substitute m = 10 and b = 15 into y = mx + b
y = 10x + 15

This was my answer for someone else question exactly like this :)
So the actually surface area can be split up by dif parts....meaning
2 side is 2.7*3.2*2 = 17.28
2 side is 3.2*2.1*2 = 13.44
2 sides is 2.1*2.7*2= 11.34
then u add up the areas = 42.06ft^2
then u look for what is the clossest...and that is 42gt^2
A 10% booking fee is added to the ticket price (I'm guessing 10% is added for each ticket)
Find 10% of the adult and child ticket:
10% of 15 = 1.5
10% of 10 = 1
find the total price for the 4 adult tickets he buys and 2 child tickets:
(15 +1.5) × 4 = 66
(10 + 1) × 2 = 22
66 + 22 = 88
1.5% will then be added if he lays by credit card :
1.5% of 88 = 1.32
total :
88 + 1.32 = 89.32
He pays a total of £89.32
45(5)=225 than multiply that by 60 because remember he only swam 5 out of 7 days a week (12x5=60) therefore 225x60= 13,500 minutes to convert to hours divide by 60 which will be 225 hours
