An investment that yielded 6% simple interest came due at the end of the
year. Dominic received a check for
the total amount (interest plus principal)
of $169.60.
What was his original investment?

principal = $160

Step-by-step explanation:

A = p(1+rt)

169.60 = p(1+0.06 x 1)

169.60 = 1.06p

p = 169.60 / 1.06 = 160

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
