Kira is trying to drink more water and juice each day. The difference in the amount of water in a jug and the amount of juice in the bottle she is drinking from is 192 ounces. She has consumed a total of 42 ounces, which is StartFraction 3 Over 32 EndFraction of the bottle of juice and StartFraction 9 Over 64 EndFraction of the jug of water. Which system of equations can be used to determine the total number of ounces in the jug of water, x, and the total number of ounces in the bottle of juice, y? x minus y = 192 and StartFraction 9 Over 64 EndFraction x StartFraction 3 Over 32 EndFraction y = 42 x minus y = 192 and StartFraction 3 Over 32 EndFraction x StartFraction 9 Over 64 EndFraction y = 42 x y = 192 and StartFraction 9 Over 64 EndFraction x StartFraction 3 Over 32 EndFraction y = 42 x y = 192 and StartFraction 3 Over 32 EndFraction x StartFraction 9 Over 64 EndFraction y = 42.
