Sally needs $20,000 in 4 years. she has $10,000 to invest. if interest is compounded continuously, what rate is required for sally to meet her goal?

rate = natural log (Total / Principal) / Years

rate = natural log (2) / 4

rate = 0.69314718056 / 4

rate = 0.1732867951 So the required rate is

17.32867951 %

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
