At the store deli, you spent $13.45 on 5 pounds of cheese. how much would it cost to buy 2 pounds of cheese?

The answer is $5.38 because first you divide 13.45 by 5 which equals 2.69. That's the cost of one pound, so to find out the cost for 2 pounds just multiply 2.69 by 2 to get the final answer of $5.38.

Hoped this helped! :)

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
