The simplified expression is 6+3i
The ending balance in the account is $18,937.5
Step-by-step explanation:
Simple Interest Equation (Principal + Interest) is A = P(1 + rt), where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate in decimal)
- t is the time the money is invested or borrowed for
Dylan deposited 15,000 in an account that pays 7.50% simple interest for 3.5 years. We need to find the ending balance in the account
∵ Dylan deposited 15,000 in an account
∴ P = 15,000
∵ The account pays 7.5% simple interest for 3.5 years
∴ r = 7.5% = 7.5 ÷ 100 = 0.075
∴ t = 3.5
- Substitute all of these values in the rule above
∴ A = 15,000(1 + 0.075 × 3.5)
∴ A = 15,000(1 + 0.2625)
∴ A = 15,000(1.2625)
∴ A = 18,937.5
The ending balance in the account is $18,937.5

Answer:
I would say constant, $19/sweater. The table doesn't go up by 2s or 3s.
Step-by-step explanation:
Let, the number of books on Monday = m
On Tuesday = 2m
On Wednesday = 2m - 6
Equation: m + 2m + (2m - 6) = 19
You can solve it:
5m = 19 + 6
m = 25/5
m = 5
In short, He sold 5 books on Monday
Hope this helps!
