Answer 1

The carton of eggs at Supermarket B is
`\boxed{\text{C}}$1.26 or 1 dollar and 26 cents}`

Explanation:

The price of a carton of eggs at SuperMarket A is $2.10

The price of a carton of eggs at Supermarket B is 40% less than the price of Supermarket A

Just to make it easier, I'm going to call Supermarket A Safeway and Supermarket B Walmart.

The price of a carton of eggs at Safeway is 100% of the price, which is $2.10

The same carton of eggs cost 40% less than 100% of $2.10 at Walmart, so 60% of $2.10

60% of something can be represented by multiplying that number by 0.6

• 60% of $2.10
• 0.6 * $2.10
• $1.26

The carton of eggs at Walmart(Supermarket B) costs $1.26
