Answer: Plan to add the same number of stores each year:
Let x be the number of stores the company adds each year. To reach at least 600 stores and no more than 800 stores in 5 years, we need:
5x + 5(5) = 600 (minimum number of stores)
5x + 5(5) = 800 (maximum number of stores)
Solving these equations, we get:
x = 119.4
So, the company can add 119 stores each year for 5 years to reach at least 600 stores and no more than 800 stores.
Plan to multiply the number of stores by the same factor each year:
Let r be the factor by which the number of stores increases each year. To reach at least 600 stores and no more than 800 stores in 5 years, we need:
5(5) r^5 = 600 (minimum number of stores)
5(5) r^5 = 800 (maximum number of stores)
Solving these equations, we get:
r ≈ 1.63
So, the company can multiply the number of stores by about 1.63 each year for 5 years to reach at least 600 stores and no more than 800 stores (rounded to the nearest whole store). For example, starting with 5 stores, the company can have approximately 8, 13, 21, 34, and 55 stores after 1, 2, 3, 4, and 5 years, respectively.
