I honestly don’t know. But the square in the bottom of the triangles indicate that it is a right triangle equaling 90 degrees. You can try using that along with other knowledge of right triangles you have. Could you possibly use Pythagorean theorem also?
The function for this would be
f(x)= 70x + 5
Plug the 4 and half hours (4.5) into the function
f(x) = (70 x 4.5) + 5
You then get 315 from multiplying 70 and 4.5. Then add the additional 5 from gasoline.
You end up with 320$ for working 4 and a half hours
