hello welcome to brainly here's your answer
Step-by-step explanation:
Let One Cup of Coffee is X and one doughnut be Y
So X+3Y=4.10 and 2X+2Y=4.60 => X +Y=2.30
=> X+3Y-(X+Y)=4.10-2.30 => 2Y=1.80 => Y=0.90
and X+0,90=2.30 => X=2.30-0.90=1.40
So answer is 1 cup of coffee is $1.40 and one doughnut is $0.90
