The amount of money, a, accrued at the end of n years when a certain amount, p , is invested at a compound annual rate, r, is given by the equation a =p(1+r)n. when joseph invests $500 in an account that pays 9% interest compounded annually, what is joe's approximate balance after 7 years? question 9 options: a) $258.38 b) $3815.00 c) $914.02 d) $932.54

-14 is the answer

hope this : ))

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

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
