Answer:
<h2>76</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>- triangles
- equation
- PEMDAS
- this is an isosceles triangle since two sides are equal therefore
- a triangle contains 180°
according to the question
2x+2+2x+2+3x+1=180
solve:
- collect like terms:7x+5=180
- substract 5 from both sides:=>7x+5-5=180-5=>7x=175
- divide both sides by 7: =>7x/7=175/7
- x=25
given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
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.
