Answer:
The rate of return in investment = 61.6% per year
Explanation:
The return on an investment is defined as the interest gained on an investment. Ideally, the return amount is supposed to be more than the amount invested, but if the reverse occurs, the rate of return is described as negative return. The Rate of Return on investment is the proportion of the investment amount which is the return on the originally invested amount. It is calculated in percentage as; (profit ÷ invested amount) × 100.
First, we will calculate the profit made on investment.
total landfill area = 44,000 m²
cost per m² = $8
Therefore total cost incurred (investment) = 44,000 × 8 = $352,000
Income
Pickups;
$14 per pickup load. Therefore, 2500 pickup loads
= 2500 × 14 = $35,000
dump-truck;
$25 per dump-truck load. Therefore, 650 dump-truck loads
= 650 × 25 = $16,250
Compactor-trucks;
$70 per compactor-truck load. Therefore, 1200 compactor truck loads
= 1200 × 70 = $84,000
Therefore, Total income = 35,000 + 16,250 + 84,000 = $135,250
Gain/Return on investment = Total investment - total expenditure
= 352,000 - 135,250 = $216,750
Rate of return on investment (%) = (profit ÷ invested amount) × 100.
= (216,750 ÷ 352,000) × 100 = 0.6157 × 100 = 61.6% (to one decimal place)
