First find the yearly payment using the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value 276475
Pmt yearly payment ?
R interest rate 0.0565
N time 30 years
Now solve for pmt
The formula change to be
Pmt=pv÷ [(1-(1+r)^(-n))÷r]
Plug in the equation above
Pmt=276,475÷((1−(1+0.0565)^(−30))÷(0.0565))=19,339.22
Now find the cost of the principle and interest after 30 years by multiplying the yearly payment by the time
19,339.22×30=580,176.60...answer
Hope it helps:-)
The correct answer is -14
In getting the concentration of the substance that has an aqueous solution of a fluoride of 0.039M, the density doesn't matter anymore you just have to multiply its solution to its molar mass that would came up to 0.7409g and then do the conversion that could lead to a 0.07409%(m/m).
