A team of astronauts is preparing a mission to the moon. The pull of gravity on the moon is different than on Earth. On the moon

erik [133]

Answer:

$(C)$ $xa+ya>\frac{1}{6}xa+\frac{1}{6}ya$

Step-by-step explanation:

For this mission, each astronaut will bring

x pounds of food; and
y pounds of gear.

Weight of Supplies of One Astronaut on the earth = (x+y) pounds

If the total number of astronauts going on the mission= a

Total Weight on the earth of the supplies of all the Astronaut $=a (x+y) pounds$

On the moon, things weigh $\frac{1}{6}$ of what they weigh on Earth.

Total Weight of the supplies of all the Astronaut on the moon $=\frac{1}{6}a (x+y) pounds$

Therefore,the inequality which correctly compares the weight of the supplies on the moon to the weight of the supplies on Earth is:

$a (x+y) pounds >\frac{1}{6}a (x+y) pounds\\xa+ya>\frac{1}{6}xa+\frac{1}{6}ya$
