Answer:
1.41 %
Step-by-step explanation:
Principal amount (P) = $500
Time (T) = 2 weeks = 2 * 7 days = 14 days
Interest = $80
So,
Interest = P*T*
=> 80 = 500 * 14 *
=> 80 = 7000 *
Flip the sides of the equation
7000 * = 80
Multiply both sides by 100
7000 * * 100 = 80 * 100
Cancel out the 100's on the top and bottom from the left side
7000 * R = 8000
Divide both sides by 7000
=
Cancel out the 7000's on the top and bottom from the left side
R = 1.41 %
So, the periodic interest rate of the loan = 1.41 %
The correct option is The Barbara equation did not consider the number of bottles of water.
Given,
The selling price of iced tea is $1.49 per bottle.
The selling price of water is $1.25 per bottle.
Equation written by the Barbara,
Here in this question Barbara multiply the selling price of bottle with the number of bottle using the coefficient x, But she did not use any coefficient for the bottle of water. The correct equation is,
where<em> y </em>is the number of water bottle sold to earn the profit of $100.
Hence the correct option is the Barbara equation did not consider the number of bottles of water.

Answer:
C, 105 Degrees
Step-by-step explanation:
So the two opposite sides of a parallelogram is equal to each other and the two adjacent angles are supplementary. So if (x+40)+3x=180, this means that 4x+40=180. This gives us 4x=140, so x=35. If we plug it back into the equation it ascertains as such: 3(35)= 105. The answer for this question and angle O is 105 degrees, or C.
