Solution: f(18.5)=31.47
Step by step solution:
I started by making an equation in slope intercept form- I found the slope, 28/17, with the points (4, 17) and (12.5, 31). Then I found the y intercept, 1, with the point (4, 17). So the equation is y=28/17x+1. Then I just plugged 18.5 where the x is and solved for y
28/17(18.5)+1=y
28/17(37/2)+1=y
1036/34+1= y
30.47+1=y
y=31.47
Keep in mind that 1036/34 is not exactly 30.47 but that 30.47 was rounded to the nearest hundredth

1 liter of petrol in London costs £1.029
Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:
Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766
Next, we convert the pounds (£) to dollar($)
Since the exchange rate is 1$ =£ 0.497
£3.8951766 in $ = £3.8951766/£ 0.497 = 7.837$
The price of London petrol in dollars ($) per gallon =$7.84 (Rounded to nearest cents)
