Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement

r+c=80

.50r+.10c=20

Step-by-step explanation:

each rose costs $0.50

each carnation costs $0.10

The number of roses is r, and the number of carnations is c.

the arrangement has a total of 80 flowers, so we have that:

r + c = 80

the cost is $20, so we have:

r*0.5 + c*0.1 = 20

so our system of equations is:

r + c = 80

r*0.5 + c*0.1 = 20

and we can also solve it; for this isolate one of the variables in the first equation:

r = 80 - c

now let'r replace this in the second equation:

(80 - c)*0.5 +c*0.1 = 20

40  - c*0.4 = 20

c = 20/0.4 = 50

this means that we have 50 carnations, and the other 30 are roses.
