The function y = 3.5x + 2.8 represents the cost y (in dollars) of a taxi ride of x miles.
1)
we have $75 and we need to determine the total distance travel by taxi with$75
Since, Amount is represnt by y
So, y =75 to find the disatnce, x
Susbstitute y = 75 in the equation and simplify
[tex]\begin{gathered} y=3.5x+2.8 \\ 75=3.5x+2.8 \\ 72.2=3.5x \\ x=\frac{72.2}{3.5} \\ x=20.62 \end{gathered}[/tex]Thus total distance travelled 20.62 miles
2)
From school to your job is about 5.5 miles, Distance x =5.5
we need to find the value of amount i.e the value of y at x=5.5
[tex]\begin{gathered} y=3.5x+2.8 \\ y=3.5(5.5)+2.8 \\ y=22.05 \end{gathered}[/tex]It cots $22.05 to take a taxi From school to your job
