Step-by-step explanation:

Rose = x

Carnation = y

According to given statement;

8x+5y=31.75 Eqn 1

x+3y=5.75 Eqn 2

$Multiplying\ Eqn\ 2\ by\ 8\\8(x+3y=5.75)\\8x+24y=46 \ \ \ Eqn\ 3\\Subtracting\ Eqn\ 1\ from\ Eqn\ 3\\(8x+24y)-(8x+5y)=46-31.75\\8x+24y-8x-5y=14.25\\19y=14.25\\Dividing\ both\ sides\ by\ 19\\\frac{19y}{19}=\frac{14.25}{19}\\y=0.75$

Cost for a carnation is $0.75
