Hi!
Let's find out how much he has to pay for each of the deals.
Deal 1
£1.75 per mile.
192 x 1.75 = 336
£336
Deal 2
15% off of £680
![\frac{x}{680} \frac{15}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B680%7D%20%5Cfrac%7B15%7D%7B100%7D%20%20)
680 x 15 = 10200
10200/100 = 102
680 - 102 = 578
£578
Deal 3
£90 per day - 1/10
90 x 7 = 630
1/10 of 630 = 63
630 - 63 = 567
£567
The cheapest deal would be Deal 1
Hope this helps! :)

Answer: C) 5
--------------
x = independent variable, y = dependent variable
Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.
-------------------
An alternative is to use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (25 - 15)/(4 - 2)
m = 10/2 <--- this expression shows up again
m = 5 <---- leading to the same answer as before
So we see that the slope formula is a more drawn out method to finding the answer.
Answer:
Stephen has 9 trees
Alice has 21 trees
Step-by-step explanation:
<u>At the beginning:</u>
Stephen = x trees
Alice = x + 12 trees
<u>At the end:</u>
Alice = (x + 12) - 4 trees
Stephen = x + 10 trees
Total = 36
Then
![((x+12)-4)+(x+10)=36\\ \\(x+12-4)+(x+10)=36\\ \\(x+8)+(x+10)=36\\ \\x+8+x+10=36\\ \\2x+18=36\\ \\2x+18-18=36-18\\ \\2x=18\\ \\x=9](https://tex.z-dn.net/?f=%28%28x%2B12%29-4%29%2B%28x%2B10%29%3D36%5C%5C%20%5C%5C%28x%2B12-4%29%2B%28x%2B10%29%3D36%5C%5C%20%5C%5C%28x%2B8%29%2B%28x%2B10%29%3D36%5C%5C%20%5C%5Cx%2B8%2Bx%2B10%3D36%5C%5C%20%5C%5C2x%2B18%3D36%5C%5C%20%5C%5C2x%2B18-18%3D36-18%5C%5C%20%5C%5C2x%3D18%5C%5C%20%5C%5Cx%3D9)
Stephen - 9 trees
Alice - 9 + 12 = 21 trees
