Below are sample questions representative of the exercises included on this worksheet and related ALG2.160 Identifying Constant Percent Change skill assessments:

Problem 1Difficulty: Mastery

A value is multiplied by 0.995 each day (discrete). If you switch to a continuous model A(t)=a·exp(k·t) with t in years (365 days), what is k per year? Round to 4 decimal places.

Solution & Explanation:Daily factor is 0.995. Over 365 days, factor is 0.995³⁶⁵. In continuous form, k = ln(0.995³⁶⁵)=365·ln(0.995) ≈ −1.8309.

Problem 2Difficulty: Mastery

Plan X grows 0.9% each month. Plan Y grows 10% each year. Assuming constant monthly change for Plan X, what is (Plan X’s percent change over 1 year) minus 10? Round to the nearest tenth of a percent.

Solution & Explanation:Plan X yearly factor is 1.009¹², so yearly percent is (1.009¹²−1)·100 ≈ 11.4%. Subtract 10 to get about 1.4%.

Problem 3Difficulty: Mastery

A quantity doubles in 9 days. If it changes by a constant percent each hour (discrete), what is the percent change per hour? Round to the nearest thousandth of a percent.

Solution & Explanation:9 days is 216 hours. Doubling means b²¹⁶=2, so hourly factor b is the 216th root of 2 (b≈1.003214). Percent change ≈ 0.321%.
