This actually is a math problem! The answer is no more than 50% of your total income. For example, if your income is $834.26 a week, you're bringing home $3370.04. You would not want your expenses to exceed $1660.75. Therefore, the answer to your question is $1405.12.

X + 18 = 5x - 38
x - x + 18 = 5x - x - 38
18 = 4x - 38
18 + 38 = 4x - 38 + 38
56 = 4x
56/4 = 4x/4
14 = x
