To determine how much Mrs. Hara will save per pair of glasses by using Company 2, we need to calculate the price per pair for each company.

Company 1 sells the glasses for $40 each.

Company 2 sells 4 glasses for $140, so we calculate the price per pair (2 glasses):

  1. First, find the price for 2 glasses from Company 2: \[ \text{Price for 2 glasses} = \frac{140}{4} \times 2 = 70 \]

  2. Now, the cost per pair of glasses from each company is:

    • Company 1: $40 (for 1 glass) × 2 = $80 (for 2 glasses)
    • Company 2: $70 (for 2 glasses)
  3. Finally, we find the savings by subtracting the price of glasses from Company 2 from the price of glasses from Company 1: \[ \text{Savings} = 80 - 70 = 10 \]

However, upon evaluating the options provided:

The only calculation and deduction imply that the actual savings per pair from Company 2 when compared to Company 1 is $10. Therefore, it looks like none of the response options directly correspond to our calculation.

Based on your options:

  • $20.00
  • $100.00
  • $75.00
  • $5.00

None of these options align with the calculated savings of $10. Please verify the details or pricing, as it appears there might be an inconsistency with the provided options.
