Laura sold 32 boxes, Kelly sold 17, and Tia sold 34 boxes. Step-by-step explanation: Let Laura's boxes be represented by L. Kelly sold L - 15, and Tia sold 2(L - 15). Therefore, the equation L + (L - 15) + 2(L - 15) = 83 can be solved as follows: 4L - 45 = 83, giving us 4L = 128, hence L = 32. Subsequently, Laura sold 32 boxes, Kelly sold 17 (which is 32 - 15), and Tia sold 34 (totaling twice Kelly's sales). The overall total is 32 + 17 + 34 = 83.
The correct answer is option B. For the variables, let x represent the number of apples and y for the number of oranges. We know that a crate contains a total of 72 pieces of fruit, leading to equation A. Additionally, since a crate holds 8 more apples than oranges, we arrive at equation B. Hence, the solution would be option B.
Answer:
Please refer to the explanation
Step-by-step explanation:
Provided parameters:
Initial population = 4000
Monthly increase = 170
Monthly decline in population = 70
Monthly growth rate in population (dt):
Starting population = 4000
Births per month = 170
However, there is a loss of 70 individuals monthly
Thus,
Births - Deaths (d) = 70
170 - d = - 70 (is there a decline?
170 + 70 = d
d equals the number of deaths
Per capita death rate:
Total deaths monthly / Initial population
= 240 / 4000
= 0.06
