Worked Solution
Step 1: Find current Drinks income.
25% of $8 000 = $2 000
Step 2: Find new Drinks income (doubles).
$2 000 × 2 = $4 000
Step 3: Find the new total income.
All other categories stay the same: $8 000 − $2 000 = $6 000 unchanged.
New total = $6 000 + $4 000 = $10 000
Step 4: Calculate Drinks as a percentage of new total.
$4 000 ÷ $10 000 × 100% = 40%
Drinks make up 40% of the new total monthly income.
Correct answer: 40%
