Number is n
Three times the sum of a number and 4.
 
= 3* ( n + 4) = 18
    3n  + 12 = 18.
     3n    =  18 - 12.
      3n   = 6
         n = 6 / 3.
           n = 2.

P= ? , r=4%, t=3 months, I=$20
Scilla [17]
<span>Answer:

P = $ 2,000.00

Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
putting time into years for simplicity,
3 months ÷ 12 months/year = 0.25 years,
then, solving our equation

P = 20 / ( 0.04 × 0.25 ) = 2000
P = $ 2,000.00

The principal required to
accumulate interest of $ 20.00
on a rate of 4% per year for 0.25 years (3 months) is $ 2,000.00.
