Future value = present value × (1 + i)t `"present value" = "future value" / (1 + i)^"t"` todd currently has $5,000. what was the value of his money four years ago if he's earned 4 percent interest each year?

$4.992,16

Step-by-step explanation:

We need the apply the equation for present value, and we suppose $5.000 is our future value

i is the interest=4%=0,04

t is the years =4

Introducing those values in the equation, we have:

"present value"=5.000/(1+0,04)⁰⁰⁴

Present value=5.000/1,00157

Present value=4992,16

And this present value for us is going to be the value 4 year before

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
