Answer:
4400
Step-by-step explanation:
For the first box on the left hand side, the answer is m < 1 + m < 2 = 180 as they are a linear pair
The first box in the right-hand column is "linear pair postulate" as its very similar to the previous line
The second box on the left-hand side is m < 1 + m < 2 = m < 2 + m < 3. Essentially we're doing replacements. Similar to how x+3 = 10 turns into 7+3 = 10 when we plug in x = 7
The second box on the right-hand side is "subtraction property of equality". We subtract "m < 2" from both sides to end up with m < 1 = m < 3
1) + $12, since it is a profit
2) -1440 ft, since it is below the sea level
3) - 22°F, since it is below
4) + 31 yards, since it is a gain.
If Jan bought 3 lamps for $23.59 each, and a sofa for $769.99, then we can add these prices together for the total amount Jan spent:
23.59 + 23.59 + 23.59 + <span>769.99 = $840.76
</span>
Now we can find out how much sales tax she owes by multiplying the total cost by the sales tax rate:
$840.76 x 7.5% = <span>840.76 x 0.075 = $63.06
</span>
Therefore the answer is B. $63.06
