Hello!
We are asked to find the number of lines the choir has to learn in time for a concert.
We're given that the concert is in 7 weeks, but they learn new lines each day, so we have to convert it to days. We know that there is 7 days in a week, we would multiply 7 weeks by 7 days, which is 49 days.
Now, we would take the total number of lines, which is 3016, and divide that by 49 days.
3016 lines / 49 days ≈ 61.55 lines/day
Since this is a real-world situation, we should round our answer is to nearest whole number, which would be 62 lines/day.
Therefore, Ester's choir needs to learn about 62 lines per day in time for the concert.
I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.
You plug in $67 for y because you need to find out what week you'll have $67 dollars in the account.
