John bought 15 pines for $3500
1 answer:
Answer:
Explanation:
If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.
Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.
John spent $3500.
140% of $3500 is $4900.
So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.
However, the question asks for the price of a single pine. To find the unit price of a single pine, divide the total revenue by 15.

Answer:
A
Explanation:
Let's solve the equation to be written as y in terms of x by adding y to and subtracting 12 from both sides:
3x - y = 12
3x - 12 = y
Now, replace y in the other expression that we want to find () with this expression 3x - 12:
Now, we also know that 8 = 2³, so substitute 2³ for 8 in the expression:
Remember that when dividing powers with the same base (in this case, the common base is 2), the result will be a single power whose exponent is the difference of the other two powers. Here, then we have:
Thus, the answer is A.
