Answer:
8
Step-by-step explanation:
4.60=0.2t+0.5f
t=20 cent coins
f=fifty cent coins
t+f=14
multiply the second equation by 0.5 to eliminate the f and subtract one equation from another.
4.60=0.2t+0.5f
-(7 =0.5t+0.5f)
-------------------------------
-2.4= -0.3t
multiply both sides by -0.3 to get 8=t. That's the # of 20 cent coins.
