104÷5.1

20,4

Step-by-step explanation:

First, we take from 1040, only 104 and look up for a number that multiply by 51 gives less or equal 102, so:

, this 2 goes to the answer

and 104 - 102 = 2

And now we use the last zero from 1040, and now we have a 20, but that number is less than 51, so we add another zero to have a 200, and we have to add another zero to the 2 of the answer

So, our answer until now is 20

Now, we add a coma to the answer (20,) and with the 200, we look up for a number that multiply by 51 gives less or equal 200, so:

And the answer until now is 20,3

and 200-153 = 47

We are in the same case, so we add a zero to get 470 and we look up for a number that multiply by 51 gives less or equal 470, so:

So the answer so far is 20,39

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
