The bank gave a loan with a 9% simple interest rate to be paid in 3 years. If $378 was paid in interest, how much was the principal?​

$1400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

P = 378 / ( 0.09 × 3 ) = 1400

P = $ 1,400.00

The principal required to

accumulate interest of $ 378.00

on a rate of 9% per year for 3 years is $ 1,400.00.

17 1/3

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
