2. luis received a discount of $24 on his new phone, which had an original price of $140. by what percentage was the original price discounted?

Explanation:

Step1: Convert percentage to decimal

$40\% = 0.4$

Step2: Calculate red rose count

$\text{Number of red roses} = 350 \times 0.4$

Step3: Set up discount percentage formula

$\text{Discount percentage} = \frac{\text{Discount amount}}{\text{Original price}} \times 100\%$

Step4: Compute discount percentage

$\text{Discount percentage} = \frac{24}{140} \times 100\%$

Answer:

1. 140 red roses must be in the order.
2. The original price was discounted by approximately $17.14\%$.
