Find the principal that will yield an interest of Rs 367.75 in 4½ years at 3½% per annum.

The principle amount = P = $ 2334.92

Step-by-step explanation:

Given

Interest amount I = Rs 367.75

Time period t = 4½ = 9/2 = 4.5 years

Interest rate r = 3½ % = 7/2% = 3.5% = 0.035

To determine

Principal P = ?

Using the simple interest formula

I = Prt

where

I = Interest amount

r = Interest rate

t = time in years

substituting I = Rs 367.75, t = 4.5 years, r = 0.035 in the equation

I = Prt

P = I / rt

   =  [367.75] / [(0.035)(4.5)]

P = $ 2334.92    

Therefore, the principle amount = P = $ 2334.92

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
