Sam gets $1000 dollars per month. She has to spend $20 a day on transportation, she also needs to buy groceries each week and have $30 extra spending money per week. How much money should be spent on food per day?

Sam makes 1,000 dollars every month. How much does she make per day?

1,000 : 30 = $33.33/day. This is her daily budget.

Transportation cost = $20/day.

Spending money/day = $30/week : 7days/week = 4.28 / day

Daily Budget:

33.33 = transport + spending money + groceries

33.33 = 20 + 4.28 + groceries Subtract 24.28 from each side:

9.05 = groceries

$9.05 per day should be spent on groceries, assuming she doesn't want to save any of her income.
