Answer:
1. r+s²=49
2. pq²=24
3. -4xy-6x²+2x²y-6y= -54
Step-by-step explanation:
1. r+s²=0+7²=49
2. pq²=(6)(2)²=6(4)=24
3. -4xy-6x²+2x²y-6y= -4(3)(2)-6(3)²+2(3)²(2)-6(2)
= -24-6(9)+2(9)(2)-12
= -24-54+36-12
= -78+36-12
= -42-12
= -54
Using the formula for simple interest, it is found that he paid $119.87 in interest.
The<u> simple interest formula</u> is given by:
- E is the amount of interest earned.
- P is the principal(the amount of money invested).
- I is the interest rate(yearly, as a decimal).
- t is the time, in years.
In this problem:
- Borrowed $2,700, thus

- Interest rate of 3.5%, thus

- From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is

Thus, the interest paid was of:

$119.87.
