Answer 1

First, we need to find the price per pair of glasses from both companies.

• Company 1 sells the glasses for $40 each.

• Company 2 sells the glasses at a rate of 4 for $140. To find the price per pair, we divide the total price by the number of glasses:

  \[ \text{Price per glass from Company 2} = \frac{140}{4} = 35 \]

Now we compare the prices:

• Company 1: $40 per glass
• Company 2: $35 per glass

To find out how much Mrs. Hara saves per pair of glasses when using Company 2, we subtract the price from Company 2 from the price from Company 1:

\[ \text{Savings per glass} = \text{Price from Company 1} - \text{Price from Company 2} = 40 - 35 = 5 \]

Therefore, Mrs. Hara saves $5.00 per pair of glasses if she uses Company 2.

The correct response is:

$5.00
