Question

The price of a dozen eggs was $1.63. The price rose m dollars. Then the price dropped $.12 per dozen. Express the current price of eggs after the two price changes. A) m + .51 B) m + 1.51 C) m + 1.63 D) m + 1.75

Answer 1

It is B because 1.63-0.12 equals 1.51 and it rose m so it will be M+1.51

Answer 2

we know that

case 1) The price of a dozen eggs was
`\$1.63`

In this moment the original price of a dozen eggs is
`\$1.63`

case 2) The price rose
`\$m`

In this moment the new price of a dozen eggs is
`\$1.63+\$m`

case 3) The price dropped
`\$0.12` per dozen

The final price of a dozen eggs is

`\$1.63+\$m-\$0.12`------>
`\$1.51+\$m`

therefore

the answer is

`m+1.51`
