Simon is 13 years old
Let x be Simon's age
Thus 4 years ago his age was (x - 4) and 2 years from now his age is (x + 2)
Hence 5(x - 4) = 3(x + 2)
distributing both sides gives
5x-20 = 3x + 6
subtract 3x from both sides of the equation
5x - 3x - 20 = 6
2x - 20 = 6
add 20 to both sides
2x = 6 + 20 = 26
divide both sides by 2
x =
= 13

Number of cone left is 75 cone
<u>Given that;</u>
Cost of each cone = $3.75 each
Starting number of cone = 300
Total amount earn = $843.75
<u>Find:</u>
Number of cone left
<u>Computation:</u>
Number of cone sale = Total amount earn / Cost of each cone
Number of cone sale = 843.75 / 3.75
Number of cone sale = 225 cone
Number of cone left = Starting number of cone - Number of cone sale
Number of cone left = 300 - 225
Number of cone left = 75 cone

Step-by-step explanation:
Answer:
You will have $623.3441462 in your account after 7 years
Step-by-step explanation:
The formula of the compounded interest is A = P
, where
- n is the number of periods
∵ You are opening a savings account with $500
∴ P = 500
∵ The bank offers 3.2% interest, compounded yearly
∴ r = 3.2% ⇒ divide it by 100 to change it to decimal
∴ r = 3.2 ÷ 100 = 0.032
∵ The interest is compounded yearly
∴ n = 1
∵ The time is 7 years
∴ t = 7
→ Substitute these values in the rule above to find A
∵ A = 500 
∴ A = 500 
∴ A = 623.3441462
∴ You will have $623.3441462 in your account after 7 years
