Answer:
t=16.2 years
Step-by-step explanation:
A=p(1+r/n)^nt
A=$20100
P=$6500
r=7%=0.07
n=4
t=?
t=ln(A/P)/n {ln(1+r/n)}
=ln(20100/6500) / 4{ln(1+0.07/4)}
=ln(3.0923)/4{ln(1+0.0175)}
=ln(3.0923)/4{ln(1.0175)}
=1.1289/4(0.0174)
=1.1289/0.0696
=16.23
To the nearest tenth
t=16.2 years

Step-by-step explanation:
Answer:
Stain required to stain the ramp = 2 quarts
Step-by-step explanation:
Area of the wheelchair ramp to be stained = Surface area of the ramp - Area of the rectangular base
Surface area of the ramp = 2(area of the triangular base) + (perimeter of the base)(height)
Area of the triangular base = 
= 
=
in²
Perimeter of the triangular base = 
= 25 +
+ 25 + 
= 50 + 
= 50 + 
=
ft
Surface area of the ramp =
+
- 25×5
= 
= 
= 187.92 square feet
Since, 100 square feet area is covered by the stain = 1 quart
Therefore, 187.92 square feet will be covered by the stain = 
= 1.8792
≈ 2 quarts
