Hunter needs 10 ounces of a snack mix that is made up of seeds and dried fruit. the seeds cost $1.50 per ounce and the dried fruit costs $2.50 per ounce. the 10 ounce snack mix costs $2.20 per ounce. let x = the amount of seeds. let y = the amount of dried fruit. how much of each snack should hunter purchase to satisfy the scenario?

Here:x = the amount of seeds, y = the amount of dried fruit.The system of equations:
x + y = 101.5 x + 2.5 y = 2.2 * 10x = 10 - y1.5 * ( 10 - y ) + 2.5 y = 2215 - 1.5 y + 2.5 y = 22y = 22 - 15y = 7x = 10 - 7 = 33 ounces of the seed and 7 ounces of the dried fruit.
 

This is a conversion. 1000m=1 km
Write the original then make parenthesis of the conversion. Because we need to cancel the m out we put it on the bottom. Since we want km as our new units it goes on the top. Now we plug in the numbers. 1 would go on top with the km and 1000 would go with the m because 1000m=1km. Now just divide and you have the answer.
600m(1km/1000m)
.6km
