Zoe practices the piano 812 minutes in 4 weeks. At what rate did she practice, in minutes per day

Step-by-step explanation

Given

Zoe practices the piano 812 minutes in 4 weeks

4 weeks=7×4

=28 days

she practice, in minutes per day=812/28

=29 minutes

So she practices 29 minutes per day

1. 45 minutes a day cycling

2.$1.55 on each cup of coffee a day

Step-by-step explanation:

1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45

2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract  15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
