san4es73 [151]

Answer:

The lowest amount would be (1 x 5) + (2019 x 1) = 2024 cents, or $20.24

The highest amount would be: (1 x 1) + (2019 x 5) = 10,096 cents, or $100.96

100.96 - 20.24 = 80.72

The difference in cents between the greatest possible and least possible amounts of money Ricardo can have is $80.72.

stella has twice as many fish in her tank as catherine .catherine has twice as many fish in her tank as rita .they have 70 fish
tiny-mole [99]
Well, we do not know how many fish Rita has, so lets represent that with y. Anyway, it says that catherine has twice as many fish as Rita. So that will be 2y. And Stella has twice as many as catherine, so that will be 2 x 2y. And that will be 4y. So Ruth has y, catherine has 2y and stella has 4y. And the total is 70. So that means that the number of fishes added together will be 70. That can be represented as;
y + 2y + 4y = 70
y is the same as 1y. And when you add y + 2y + 4y, you will get 7y. So
7y=70
Divide the both sides by 7. That will be;
y= 7 . So Rita has 7 fishes. Hope i helped.
