PLEASE HELP NOW Ava spends about 45 minutes studying each day. She also practices the piano for an average of 20 minutes per day, and she practices soccer 1.5 hours three times a week. If Ava decides to reduce the time she does each activity by 16, find the total number of hours she spends studying and practicing in a year with a reasonable level of accuracy.

1. Ava spends 45min per day studying

reduce this amount be 16min we have=45-16=29min

in a year she will spend 365*29= 10585min

2. She also practices the piano for an average of 20 minutes per day

reduce this amount be 16min we have=20-16=4min

in a year she will spend 365*14= 5110min

3. She practices soccer 1.5 hours three times a week.

in minutes 1.5hours is 90min three times a week

in a day 90*3/7= 270/7=38.57

reduce this amount be 16min we have=38.57-16=22.57min

in a year she will spend 365*22.57= 8238.05min

in total for the year she spends studying and practicing

=10585+ 5110+8238.05

=23933.05min to hours =23933.05/60

=398.88hours
