Walter works 5 days a week in a fast-food chain and earns $5 per hour. Since he is a working student, he can only work 4 hours a day and allocates 3/4 of his weekly earning for his schooling. How much does he allocate for school?
How much does Walter earn in a day? ** Walter's daily earning is $5 x 4 = $<<5*4=20>>20.
How much does Walter earn in a week? ** So he earns $20 x 5 = $<<20*5=100>>100 per week.
How much does Walter allocate for school? ** Therefore, he allocates $100 x 3/4 = $<<100*3/4=75>>75 for his school.
