The Price family decides they want to spend less than 300 minutes per week on screens. On Sunday, they watched a movie that was 84 minutes. If they want spread the rest of their allotted screen time evenly over the next 6 days, how many minutes can they spend on their screens each day?

36 min/day

Of the 300 min/week allocated to spend on screens, 84 min has been already spent for the current week, which means that 216 min is left:

300 min - 84 min = 216 min

Of the 216 min left, it can be split evenly between 6 days if 36 min is spent each day on screens:

216 min ÷ 6 days =  36 min/day

∴ they can spend 36 min on their screens each day.

to plan an idea out before

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
