A seminar is offered to a school for their teachers. The regular seminar fee is $150 but they offer a 5% discount if they register 2 days before the scheduled seminar. The school registered 10 teachers for the seminar a week before the schedule and it also released a $10 food allowance for each of the teachers. How much did the school spend in all?
The school got a $150 x 5/100 = $<<150*5/100=7.50>>7.50 seminar fee discount for each teacher.
Each teacher's seminar fee costs $150 - $7.50 = $<<150-7.5=142.50>>142.50.
So, ten teachers' seminar fees cost $142.50 x 10 = $1425.
The food allowance for 10 teachers amounts to $10 x 10 = $<<10*10=100>>100.
Therefore, the school spent a total of $1425 + $100 = $<<1425+100=1525>>1525.
