Anyone know the answer at all?

15 years

Step-by-step explanation: Begin by writing the interest formula shown below.

Interest = principal · rate · time

Filling in the formula, the interest is $270,000.

The principal or the amount invested is $150,000.

The rate is 12% or 0.12 and we don't know the time so we use the variable t.

So we have the equation 270,000 = (150,000)(0.12)(t).

On the right side of our equation, we multiply 150,000 times 0.12 to get 18,000 and we have 270,000 = 18,000t.

Now to solve for t, we divide both sides of the equation by 18,000 to get 15 = t which means that our principle must be invested for 15 years to earn $270,00 in interest.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
