Macy's is having a one-day 35% off special. If Prachisha bought $140 worth of items, what would the final bill total apply applying the discount of 35%? When Prachisha checked out they charged her sales tax of 7.25%. How much did she pay for the items?

Ithink the answer would be knew

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.
