Answer:

part a


5r + 4d = 32


r + 6d = 22

part b

the value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece

Explanation:

part a

for part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost

part b

solve the two equations simultaneously or by substitution.

let's do simultaneous

multiply the secondequation by 5


5r + 4d = 32


5r + 30d = 110

subtracting the two,


26d = 78

therefore


d = 3 dollars

find the value of roses,


5r + 4(3) = 32 \\ 5r = 32 - 12 \\ r = 4
