Dan invests £1600 into his bank account. He receives 3.5% per year simple interest. How much will Dan have after 2 years? Give your answer to the
nearest penny where appropriate.

171200 pennies

Step-by-step explanation:

Amount after 2 years = Principal + Interest

Given

Principal = £1600

Rate = 3.5%

Time = 2years

Get the interest

Interest = PRT/100

Interest = 1600*3.5*2/100

Interest = 32 * 3.5

Interest = £112

Get the amount after 2 years;

Recall that:

Amount after 2 years = Principal + Interest

Amount after 2 years = 1600 + 112

Amount after 2 years  = £1712

Hence the amount Dan will have after 2 years is £1712

1712 pounds = (1712 * 100)penny

1712 pounds = 171200 pennies

Step-by-step explanation:

We can use the Rational Root Test.

Given a polynomial in the form:

Where:

- The coefficients are integers.

- is the leading coeffcient ()

- is the constant term

Every rational root of the polynomial is in the form:

For the case of the given polynomial:

We can observe that:

- Its constant term is 6, with factors 1, 2 and 3.

- Its leading coefficient is 2, with factors 1 and 2.

 Then, by Rational Roots Test we get the possible rational roots of this polynomial:
