    Answer:

    2 dozens, $41

    Step-by-step explanation:

    Given data

    Man Street Florist charges

    $18 for a dozen roses and a

    $5 delivery fee

    let the number of dozens be x

    and the total charge for x dozens be y

    hence

    y= 18x+5————–1

    Blooms and Bouquets

    charges $20 for a

    dozen roses and a $1

    delivery fee.

    let the number of dozens be x

    and the total charge for x dozens be y

    hence

    y= 20x+1 ————-2

    Equate 1 and 2 we have

    18x+5=20x+1

    20x-18x= 5-1

    2x= 4

    x= 4/2

    x= 2

    Hence the number of dozens is 2

    the cost is (put x= 2 in eqn 1 or 2)

    y= 20(2)+1

    y= 40+1

    y= $41
