if we consider x=2
than y should be y=0.4667.
Because,
Actual price of dozen roses is 2.80 dollars.
so for x=1 rose she will have to pay y=0.233

Same way for x=2,y=0.4667

12 rose cost=24.80 (as she got benifit of 80cents)
with 2dollar cost....2(2+10)=24
so x= 2
so 24.80/12=2.13
y=4.26

1 rose=y/x
now
y/x-2=80/(100*12)
y=31
x=15

x for y dollars
x/12 dozen----for y dollars
1 dozen------- y*12/x

(x+10)/12 dozen-------2 doller
x=14

now for y

12y/x =12y/(x+10) +80/100(12y/x)

solve y= 1.9
14 roses
for 1.9 dollers
i think i m right logicaly also
14+10 roses for 2 doller
so y cant greater then 2
