Final answer:
To determine what percent of the family's daily income is for the children's allowance, calculate the total daily income based on the food expenditure being 40%, then find the percentage the allowance represents. The children's allowance is found to be 15% of the family's daily income.
Step-by-step explanation:
The question involves calculating what percent of the family's daily income is allocated for the children's allowance. We are given that the family spends T 600.00 a day on food, which is 40% of their daily income. From this, we can determine the family's total daily income by using a simple proportion, where 40% (or 0.40) of income corresponds to T 600.00:
T 600.00 = 0.40 × (Total Daily Income)
Total Daily Income = T 600.00 / 0.40
Total Daily Income = T 1500.00
Now, to find out what percent of the family's daily income the children's allowance of P225.00 represents, we use the formula:
Percent for Children's Allowance = (Children's Allowance / Total Daily Income) × 100
Percent for Children's Allowance = (P225.00 / T 1500.00) × 100
Percent for Children's Allowance = 15%
Therefore, the children's allowance is 15% of the family's daily income.
