Rule start at 5 and 1/2 add 1 1/5

Margaret [11]

Answer:

The solution is $6\frac{7}{10}$ .

Step-by-step explanation:

It is given that rule start at $5\frac{1}{2}$ add $1\frac{1}{5}$ .

From the given information, we get the expression

$5\frac{1}{2}+1\frac{1}{5}$

Simplify the complex fraction.

$\frac{10+1}{2}+\frac{5+1}{5}$

$\frac{11}{2}+\frac{6}{5}$

Taking LCM, we get

$\frac{11\times 5+6\times 2}{2\times 5}$

$\frac{55+12}{10}$

$\frac{67}{10}$

$6\frac{7}{10}$

Therefore the he solution is $6\frac{7}{10}$ .

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

$\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100$

= $\frac{0.16 n }{n} \times 100 = 16\%$

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.
