Answer:
$ 97
Step-by-step explanation:
Total payment = A + b = 488 + 294 = 782
half of bills = 782 /2 = 391
B owe to a: 488 - 391 = 97
check: 97 + 294 = 391
- 610
12
x will be the age of her younger brother
34 = 2x + 10
She is ten more than twice his age
- 10 - 10
Then she twice his age
24 = 2x
÷2 ÷2
So his age is 12
x = 12
