Answer:
The total amount that all three friends have = $258
Step-by-step explanation:
Three friends: let their initial money be Ami's money =A, Jan = B, Toy = C
Toy started with $36 and ended with same amount
C = $36
After Ami gives, She is left with= A-x
Jan becomes= 2B
Toy becomes= 2C = 2×36 = 72
After Jan gives, Jan is left with = 2B-y
Ami now has = 2(A-x)
Toy now has = 2(72) = 144
After Toy gives, Toy is left with= 144-z
Ami now has = 2(2)(A-x) = 4(A-x)
Jan now has = 2(2B-y)
Since Toy is left with $36 at the end:
36 = 144-z
z = 144-36 = 108
So Toy spent $108 to double his two other friend's money
Both Amy and Jan had $108 in total when Toy had $144
Difference between the deductions across = $108
The total amount that all three friends have = 144+108
The total amount that all three friends have= $258
