Reikos goal is to practice the drums for at least 800 minutes per week. This week, reiko already has practiced 175 minutes. If she practices for 35 minutes each session, Reiko wamts to know how many sessions are left to make her goal.

Number of sessions remaining ≅ 18 sessions

Step-by-step explanation:

Total amount of time per week = 800 minutes

Amount of time remaining = 800 - 175 = 625 minutes

Number of minutes per session = 35 minutes

Number of sessions remaining = 625/35 = 17.85 sessions ≅ 18 sessions

18 sessions

Step-by-step explanation:

First we need to know how much time Reiko still needs to practice this week. If the total is 800 minutes and he already did 175, there is 800-175 = 625 minutes left.

In each session, Reiko practices 35 minutes, so we can make a rule of three:

1 session - > 35 minutes

X sessions - > 625 minutes

1/X = 35/625

X = 625/35

X = 17.8571 sessions

Reiko needs 18 sessions to make her goal.
