<human>:  Jezebel needs to buy two dozens of red roses and 3 pieces of sunflowers for a bouquet that she is going to arrange. Each red rose costs $1.50 and each sunflower costs $3. How much will Jezebel pay for all those flowers?
<bot>: How many red roses does Jezebel need to buy? ** Jezebel needs to buy 2 x 12 = <<2*12=24>>24 red roses.
How much will 24 red roses cost? ** Twenty-four red roses will cost 24 x $1.50 = $<<24*1.5=36>>36.
How much will 3 sunflowers cost? ** Three sunflower will cost 3 x $3 = $<<3*3=9>>9.
How much will Jezebel pay for all those flowers? ** Thus, Jezebel will pay $36 + $9 = $<<36+9=45>>45 for all those flowers.
