Points R and S on the coordinate grid below show the positions of two midfield players of a soccer team: Coordinate grid shown from negative 4 to positive 4 on x-axis and negative 4 to positive 4 on y-axis. From the origin, point R is 1 unit to the left and 3.5 units down. From the origin, point S is 1 unit to the left and 3.5 units up.

Which statement best describes the relationship between the positions of the two midfield players?

S is R reflected across the y-axis; only the signs of the x-coordinates of R and S are different.
S is R reflected across the y-axis; only the signs of the y-coordinates of R and S are different.
S is R reflected across the x-axis; only the signs of the x-coordinates of R and S are different.
S is R reflected across the x-axis; only the signs of the y-coordinates of R and S are different.

d. Since the finance charge for the 24 month loan is lower, this loan will save more.  

Step-by-step explanation:

Since, The monthly payment formula of a loan,

Where, PV is the principal value of the loan.

r is the interest rate per period

n is the number of period,

For, 36 months loan, monthly payment,

=

=

=

Thus, the total finance charge =

Again,

For, 24 months loan, monthly payment

=

=

=

Thus, the total finance charge for this loan =

Since, 8190.616 > 7752.35

Thus, the finance charge for 24 month loan is less than that of 36 month loan.

⇒ Since, the finance charge for the 24 month loan is lower, this loan will save more.
