Answer:
1. Causes: commercial production of many chemicals massive use of chemicals in food, agriculture, medicine, and industry
2. Consequences: increase in reproductive disorders contamination of soil, air, and water bioaccumulation and biomagnification of toxins in the food chain.
3. Solutions: consumer choice of low-toxicity products stricter regulations requiring that consumer products be thoroughly tested before being released to market.
Explanation:
This factors could lead to more toxic substances being released into the environment (causes), the consequences that result from toxic substances in the environment, and possible solutions to save environmental degradation.

What is the lettuce market?</h3>
- Lettuce is divided into two types: head (iceberg) and leaf (romaine, butterhead, and leaf).
- Since colonial times, lettuce has been farmed in the United States.
- The ice shipping industry emerged in the western states in the early 1900s, boosting the range and appeal of lettuce.
- Only potatoes outnumber lettuce salads in terms of annual consumption per capita.
- In 2015, the annual consumption of all varieties of lettuce was 25.8 pounds per person, with head lettuce accounting for 51% (13.3 pounds per person).
- Consumption of lettuce was about the same as in the preceding three years, but down approximately 20% from ten years before.

Answer:
A. -$272,638
Explanation:
Firstly, we need to calculate the total present value of initial investment plus all operating cost of the project. Then we will use that amount to solve for equal-amount annual operating cost.
Total present value of the project is -689,000 - 41,000/(1+13%) - 41,000/(1+13%)^2 + ... + 41,000/(1+13%)^4, or -810,953.32 (negative sign mean cost).
So, the equivalent annual cost of an oven is -272,638.
The equation solving problem can be made easily using Excel or BA II plus calculator.
