hoped I helped! i had messed up the first time lol
2 x 10⁻²
I place ⁻² as the negative powers of ten because I counted two places from the original position of the decimal to the number 2. The direction from the decimal is going to the right.
The negative or positive powers of ten determined by the direction of the decimal point. If it moves to the right then it is negative. If it move to the left then it is positive.
For example. 2000 in scientific notation.
The decimal point is located after the 3rd zero. According to the rule of scientific notation, only one digit must remain before the decimal point, Thus, 2000 is 2.000
The decimal point moved three place to the left from its original position. So its power of ten is positive three.
2000 = 2 x 10³

Answer:
see below
Step-by-step explanation:
The costs are
2230.80 + .03 b where b is the board foot
the income was 1.13b
Profit is income - costs
Profit = 1.13b - (2230.80 + .03 b)
Distribute
= 1.13b - .03b - 2230.08
= 1.10b - 2230.08
Profit is when the money is greater than 0
(breaking even is 0)
0 <1.10b - 2230.08
Add 2230.08 to each side
2230.08 < 1.10b - 2230.08 + 2230.08
2230.08 < 1.10b
Divide by 1.10
2230.08/1.10 < 1.10b/1.10
2027.345455 <b
They must sell at least 2027.345 board feet of lumber per day to make a profit
