# Problem-solving practice 1 question watch

1. The answer to the question is 16, can someone explain to me how?
'A machine makes 48 bolts every hour.
The machine makes bolts 7.5 hours each day, on 5 days of the week.
The bolts are packed into boxes. Each box holds 30 bolts.
How many boxes are needed for all the bolts made each week?'
2. To know how many boxes are needed each week you first need to work out how many bolts are made in a week.

48 (bolts per hour) x 7.5 (hours per day) = 360 (bolts per day)
360 (bolts per day) x 5 (days per week) = 1800 (bolts per week)

Each box holds 30 bolts. So, 1800 / 30 = 60

Therefore I get 60 boxes are needed. But you say the answer is 16... hmmmm

Dammit! I am terribly sorry, the answer is 60 - you're right. My apologies, I was looking at the wrong answer to the question in my revision workbook.
