Alice and bernice had some money in the ratio 7:3. After alice Had given BErnice some money, the ratio of the amount of money alice had to the amount of money BErnice had became 7:13. Bernice had $204 more than alice in the end. How much money did alice give bernice

Alice gave $238 to Bernice.

Step-by-step explanation:

Let the amount of Alice has be 7x.

Let the amount of Bernice has be 3x.

Let the amount given to Bernice be y

Amount left with Alice = 7x-y

Amount left with Bernice = 3x+y

After giving some amount Bernice, ratio of money left with Alice to Bernice  : 7 :13

91x-13y=21x+7y

70x=20y

..[1]

Bernice had $204 more than Alice in the end.

(3x+y)-(7x-y) = 204

-4x + 2y = 204

-2x + y = 102..[2]

Using value of x from [1] in [2] :

y = $238

Alice gave $238 to Bernice.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
