Answer:
x=-12 (BUT IS EXTRENUS)
Step-by-step explanation:
If u dont know what extraneous is, dont worry about it...
R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.
C) 18/1000 because .18 is out of 100 so in this case you just add a zero!! :)
First you do the parentheses wich is (3 + 1 ) and that equals 4 and now you do 6 times 1 and that eqal 6 and then you multiply 6 by 4 and the answer is 24
