Cayden and Jayden had a total of $784. After Cayden spent 1/6 of his money on food and Jayden spent $124 on toys, they had the same amount left. How much money did Cayden have at first?
Let's say cayden had x dollar. So Jayden had (784-x) dollar from 1st information.
From 2nd information:
x-x/6=(784-x)-124,
or, x*11/6=660
or, x=360.
So, cayden had 360$ at first.
Let, Cayden had $x and Jayden had $y.
According to the question,
x + y = 784 ...............(1)
and, x - \({x \over 6}\frac{}{}\) = y - 124
5x - 6y = -744 ................(2)
Solving equation (1) and (2)
eq(1) *6 + eq(2)
6x + 6y = 4704
5x - 6y = -744
...............................................
11x = 3960
x = 360
Therefore, Cayden had $360 at first.
Let the amount clayden has be X
Given :
sum of money clayden and jayden have=$784
So x+ amount jayden has =$784
Amount jayden has=$784-x
Clayden spent \( {1 \over 6}\frac{}{}\) =\({1 \over 6}\frac{}{}\)* X
So amount left with clayden=x-\(x = {x \over 6}{}^{}\frac{}{}\)
Amount left with clayden =\( {5x \over 6}\frac{}{}\)
Jayden spends $124
So amount left with jayden = $784-$124-x
So amount left with jayden=$660-x
Given :both have same amount left
Hence - 660-x=\( {5x \over 6}\frac{}{}\)
660*6-6x=5x
660*6=11x
60*6=x
360=x
Amount clayden has =$360
c+j =784
left money
\( {5c \over 6}\frac{}{}\) = j- 124
\( {5c \over 6}\frac{}{}\)=784-c-124
\( {11c \over 6}\frac{}{}\)=660
c=360 (ans)
