Question

Rogers is decreasing the price for its 5GB phone/data plan. The original price was $65. Now the same plan is for $55. By what percent did the cost decrease?

Answer 1

15.3846% Percentage Discount

Explanation:

• Starting value : 65
• Final value : 55

Using formula,

⟼
`\sf Percentage\: Discount = (Starting \:Value - Final\: Value)/(Starting \:Value) × 100`

⟼
`\sf \: (65 - 55)/(65) * 100`

Substract 55 from 65

⟼
`\sf \: (10)/(65) * 100`

Divide 10 by 65

⟼
`\sf \: 0.153846 * 100`

Multiply

⟼
`\sf \: 15.384`%
