Question

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y). m + n = 1000 0.05m + 0.06n = 57

Answer 1

You can do this problem by the elimination method.

Multiply m + n = 1000 by .05.

You get -.05 -.06 = -50.

Add this to .05m + .06n = 57.

You get .01n = 7

n = 700

m + 700 = 1000

m = 300

(300,700)
