Jerome bought 15 videos from a department store. Some videos were new releases, x, which cost $19, and some videos were classics, y, which cost $8. He spent a total of $164 on the videos. Which system of equations is set up correctly to model this information?
A(x + y = 15. 19 x + 8 y = 164.
B(x + y = 15. 8 x + 19 y = 164.
C(x + y = 164. 19 x + 8 y = 15.
D(x + y = 15. 19 x minus 8 y = 164.

Jon has to choose which variable to solve for in order to be able to do the problem below in the most efficient manner.

6 x + 3 y = 27. 5 x + 2 y = 21.

Which variable should he choose so that he can use substitution to solve the system?
A(Jon should solve for y in the first equation because the coefficients can be reduced by a common factor to eliminate the coefficient for y.
B(Jon should solve for x in the first equation because the coefficients can be reduced by a common factor to eliminate the coefficient for x.
C(Jon should solve for y in the second equation because the coefficients can be reduced by a common factor to eliminate the coefficient for y.
D(Jon should solve for x in the second equation because the coefficients can be reduced by a common factor to eliminate the coefficient for x.

In his pocket, Hamid has $2.95 in dimes and quarters. If there are 16 coins in total, which system represents the number of dimes and quarters that Hamid has?
x + y = 16. 0.10 x + 0.25 y = 2.95.
x + y = 16. 0.05 x + 0.25 y = 2.95.
x + y = 2.95. 0.10 x + 0.25 y = 16.
x + y = 16. 0.01 x + 0.25 y = 2.95.
