Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

         = \frac{9}{12} years

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

Interest = Principal \times Rate \times time

116.25=1550 \times r \times \frac{9}{12}

r= \frac{116.25 \times 12}{1550 \times 9}

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

Solve this equation 4(2)-3= 2(2) + 9​
strojnjashka [21]

Answer:5=13

Step-by-step explanation:

Open parenthesis so you do 4 time 2 and 2 times 2. you get 8-3=4+9. 8-3=5 and 4+9=13. So your final answer is 5=14. I am not sure if you can simplify it further.
