Answer:
f(x)=
1. 48x when x < or = 3,
2. 45x when 4 < or = x < or = 8
3. 42x when 9 < or = x < or = 19
4. 38x when x > 19
Step-by-step explanation:
3 boxes or less = Cost of tiles = $48
4 - 8 boxes ; cost = $45
9 - 19 boxes ; cost = $42
> 19 boxes ; cost = $38

The ramp is simply a right triangle when viewed from the side. The rise is the height of the triangle and the run is the length or base. The slope of the ramp is the angle that the ramp makes with the ground. Plug those values into the formula for tanФ = opposite/adjacent or rise/run and solve for Ф. You should end up with 0.23
