Answer:

The expression is equal to zero for the given values

Step-by-step explanation:

The correct question is

Evaluate start fraction, 1, divided by, 3, end fraction, m, minus, 1, minus, start fraction, 1, divided by, 2, end fraction, n when m=21 and n=12

we have the expression

$\frac{1}{3}m-1-\frac{1}{2}n$

we know that

To evaluate the expression substitute the given values of m and n

For m=21 and n=12

$\frac{1}{3}(21)-1-\frac{1}{2}(12)$

solve the multiplications

$7-1-6$

solve the subtraction

$7-7\\0$

therefore

The expression is equal to zero for the given values

Mary wants to buy a new house but needs money for the down payment. Her parents agree to lend her money at an annual rate of 2%,

lukranit [14]

Answer:

a) Simple interest paid = $360

b) Total repayment amount = $6360

Step-by-step explanation:

It is given that:

Principal, P = $6000

Rate of interest, R = 2%

Time, T = 3 years

(a) Total interest paid:

Formula for Simple Interest is given as:

$S.I. = \dfrac{P \times R \times T}{100}$

Putting the values of P, R and T to find out Simple Interest: $\\\Rightarrow S.I. = \dfrac{6000 \times 2 \times 3}{100}\\\Rightarrow S.I. = \$360$

(b) Total repayment amount:

We know that formula for total amount is given as:

Amount = Principal + Simple Interest

Amount = 6000 + 360 = $6360

So, total repayment amount = $6360

So, the answers are:

a) Simple interest paid = $360

b) Total repayment amount = $6360
