Mrs. Hara wants to purchase blue light blocking glasses for her family. Company 1 sells the glasses for $40 each, and Company 2 sells the same glasses at 4 for $140. How much will Mrs.
Hara save, per pair of glasses, if she uses Company 2? (1 point)
A. $5.00
B.$20.00
C. $75.00
D. $100.00
To find out how much Mrs. Hara will save per pair of glasses if she uses Company 2, we need to compare the price of Company 1 with the price of Company 2 per pair.
Company 1 sells the glasses for $40 each, so the price per pair is $40 * 1 = $<<40*1=40>>40.
Company 2 sells the glasses at 4 for $140, so the price per pair is $140 / 4 = $<<140/4=35>>35.
To find out how much Mrs. Hara will save, we subtract the price per pair of Company 2 from the price per pair of Company 1: $40 - $35 = $<<40-35=5>>5.
Therefore, Mrs. Hara will save $5 per pair of glasses by using Company 2.
Answer: A. $5.00
To find out how much Mrs. Hara will save per pair of glasses if she uses Company 2, we need to compare the prices of the two companies.
Company 1 sells the glasses for $40 each.
Company 2 sells the same glasses at 4 for $140.
To find the price per pair of glasses for Company 2, we divide the total price by the number of pairs. Since 4 glasses make 2 pairs, the price per pair for Company 2 is $140 / 2 = $70.
To find the difference in price per pair between the two companies, we subtract the price per pair of Company 2 from the price per pair of Company 1: $40 - $70 = -$30.
Since Mrs. Hara wants to save money, a negative difference is not possible. Therefore, the correct answer is:
A. $5.00
To determine how much Mrs. Hara will save per pair of glasses if she uses Company 2, we need to compare the prices of both companies.
Company 1 sells the glasses for $40 each, while Company 2 sells 4 glasses for $140.
To find the price per pair of glasses at Company 2, we calculate the average price per pair:
$140 รท 4 = $35
Therefore, the price per pair of glasses at Company 2 is $35.
To find out how much Mrs. Hara will save, we subtract the price per pair of glasses at Company 2 from the price per pair of glasses at Company 1:
$40 - $35 = $5
Therefore, Mrs. Hara will save $5 per pair of glasses if she uses Company 2.
The correct answer is A. $5.00.
