A person invested \$3,700$3,700 in an account growing at a rate allowing the money to double every 6 years. How much money would be in the account after 14 years, to the nearest dollar?

3700 x 2 = 7400 plus 1233.333... ≈ 8633

Step-by-step explanation:

Since the money (3700) doubles every 6 years we know that we multiply it by 2 (6 years times 2 = 12 years) but we still have 2 years. 2 years of 6 years = 1/3 more. 1/3 of 3700 ≈ 1233. Add 1233 to 7400 to get 8633, the answer.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
