Q. In a company's first year in operation, it made an annual profit of $129,000. The profit of the company increased at a constant 25% per year each year. How much total profit would the company make over the course of its first 8 years of operation, to the nearest whole number?Answer:
Determine initial profit and rate: Determine the initial profit and the annual increase rate.The initial profit is $129,000, and the profit increases by 25% each year.
Calculate profit for each year: Calculate the profit for each year using the formula for compound interest, which is P=P0×(1+r)n, where P0 is the initial amount, r is the rate of increase, and n is the number of years.For the first year, the profit is $129,000.
Calculate profit for second year: Calculate the profit for the second year.The profit for the second year would be $129,000×(1+0.25)=$129,000×1.25.
Perform calculation for second year: Perform the calculation for the second year.$129,000×1.25=$161,250.
Calculate profit for subsequent years: Continue this process to calculate the profit for each subsequent year up to the eighth year. We will use the formula P=P0×(1+r)n for each year, incrementing n by 1 each time.
Calculate total profit over 8 years: Calculate the total profit over the 8 years by adding the profit of each year.This requires calculating the profit for each year and then summing them up.
Use loop or summation formula: Use a loop or a summation formula to calculate the total profit. Since this is a geometric series, we can use the formula for the sum of a geometric series, which is S=P0×[1−(1+r)1−(1+r)n], where S is the sum, P0 is the initial amount, r is the rate of increase, and n is the number of terms.
Substitute values into formula: Substitute the values into the formula to find the total profit. S=$129,000×[1−(1+0.25)1−(1+0.25)8].
Perform calculation: Perform the calculation.S=$129,000×[(1−1.25)(1−1.258)].
Calculate sum using calculator: Calculate the sum using a calculator or software to ensure accuracy.S=$129,000×[(−0.25)(1−1.258)].
Calculate value of 1.258: Calculate the value of 1.258.1.258=5.960464477539063.
Substitute value into sum formula: Substitute this value into the sum formula.S=$129,000×[(−0.25)(1−5.960464477539063)].
Calculate numerator of fraction: Calculate the numerator of the fraction. 1−5.960464477539063=−4.960464477539063.
Calculate total sum: Calculate the total sum.S=$129,000×[−0.25−4.960464477539063].
Perform final calculation: Perform the final calculation.S=$129,000×19.84185791015625.
Calculate total profit: Calculate the total profit to the nearest whole number.S≈$(129,000×19.84185791015625)≈$2,559,599.57.
