The monthly payment on a \$90,000 mortage at a rate of 7.5% for 30 years

R = Pi/1 - (1 + i)^-n] where R = the monthly payment, P the ampunt borrowed, i = the periodic decimal interest rate and n = the number of interest bearing periods.

Therefore, P = 90,000(.00625)/[1 - (1.00625)^-360] = \$629.29.
