Solution given
let boys be x and girls be y.
now
according to the question;
x+y=575

2x=575+54
x=629/2
x=314.5
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷( r/k)]
Pv present value?
PMT monthly payment 425
R interest rate 0.055
K compounded monthly 12
T time 1 year
Pv=425×((1−(1+0.055÷12)^(
−12))÷(0.055÷12))
=4,951.26
