Answer:
The interest rate is 7.58%
Step-by-step explanation:
Compound continuous interest can be calculated using the formula:
A = P
, where
- A is the future value of the investment, including interest
- P is the principal investment amount (the initial amount)
- r is the interest rate in decimal
- t is the time the money is invested for
∵ Angus has $3,000 he want to invest
∴ P = 3000
∵ The interest rate is compounded continuously
∵ Angus has $5,500 in 8 years
∴ A = 5500
∴ t = 8
→ Substitute them in the rule above to find r
∵ 5500 = 3000
→ Divide both sides by 3000
∴ 
=
→ Insert ㏑ in both sides
∵ ㏑( ) = ㏑()
→ Remember ㏑(
) = n
∴ ㏑( ) = 8r
→ Divide both sides by 8
∴ 0.07576697545 = r
→ Multiply it by 100% to change it to a percentage
∴ r = 0.07576697545 × 100%
∴ r = 7.576697545 %
→ Round it to the nearest hundredth
∴ r ≅ 7.58
∴ The interest rate is 7.58%
If I had to choose a business to start off with I would start a lemonade stand With cookies
First let's do the lemonade Side Let's say I put $100 into the business And it cost a dollar per lemon $5 for 10 lb of sugar It takes about five lemons about and a pound of sugar to make one batch that makes about 20 cups of Lemonade Each cup of lemonade for cost me roughly $0.50 I would then sell Each cup of lemonade for $0.75 and make a 5 profit Now let's talk about the cookie portion of the business You have to get milk flour sugar and salt Together that cost maybe $10 per batch Of 50 cookies Which cost roughly $0.20 to Make You can sell them at with a profit of $0.05 for $0.25 After $25 Prophet.So overall you will make roughly $30

Your equation or notation would be: 12(6+5)
Any odd number multiplied by another will result in an ofd number. ex. 9x7=63 You can multiply any two odd numbers and solve.
