The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
2/5m = 750
m = 750 * 5/2
m = 3750/2
m = 1875 <== monthly income
