Please help me?!! This is due tomorrow and it’s super important! If you can do the whole page I’d be awesome thanks

1a. 1/2 * $7.99 is $3.995, which rounds to $4.

1b. 2 1/4 * $10.95 is $24.6375, which rounds to $24.64.

1c. 3/4 * $13.59 is $10.1925, which rounds to $10.19.

1d. 2/3 * $8.97 is $5.98.

2. 1/3 * $8.97 is $2.99. 75% more is $5.2325, which rounds to $5.23.

3. 1/2 * $13.59 + 1/2 * $10.95 is $6.795 + $5.475 is $12.27. $13.59 - $12.27 is $1.32.

4. You can round the costs of the pastrami and corned beef to whole numbers. If the pastrami is $14 and the corned beef is $11, it will be easier. 1/2 of $11 + 1/2 of $14 is $5.5 + $7, which is $12.5. $14 - $12.5 is $1.5, which is just around my answer of $1.32.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
