Answer:

45 dozen must be sold to make a profit of $90

Step-by-step explanation:

Cost price of 1 dozen of flowers = $3

Selling price  of 1 dozen of flowers = $5

Profit = SP - CP

Profit = $5-$3

Profit = $2

So, Profit per dozen = $90

No. of dozen must be sold to make a profit of $90 = \frac{90}{2}=45

Hence 45 dozen must be sold to make a profit of $90

Answer:

  • System is given below

Step-by-step explanation:

  • Let (applicable to all three lines below)
  • Hard candy = x kg with price $1.60/kg
  • Gummy worms = y kg with price $2.20/kg
  • Total weight = 50 kg with mixed price $1.75/kg

<u>Required equations:</u>

  • x + y = 50                        total weight
  • 1.60x + 2.20y = 50*1.75      total price

=========================================

<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>

<u>Simplify the second equation and solve by substitution x = 50 - y:</u>

  • 1.6(50 - y) + 2.2y = 87.5
  • 80 - 1.6y +2.2y = 87.5
  • 0.6y = 7.5
  • y = 7.5/0.6
  • y = 12.5

<u>Find the value of x:</u>

  • x = 50 - 12.5 = 37.5

<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg
