He will pay $1950. there are 52 weeks in a year and 52x.75=39 since it is $50 per lesson you do 39x50=1950, so this is how much he pays after 3/4 of a year.
You’ve got to work out 3/4 of the year first, that’s 75%, after you need to work out how many weeks are in those days so you divide it by 7 then divide that answer by $50 and hopefully you get your answer. hope this helps
