Question

Of the 100 students that were surveyed 36 students say

they were on their phone less than one hour a day. Of the
55 females, 40 use their phone more than one hour a
day. How many males say they use their phone less than
one hour a day?
HELP

Answer 1

15 females say they use their phone less than an hour a day

36 - 15 = 21 males that use their phone less than an hour a day

(equation above is the total number of students that use their phone less than an hour a day, with the 15 females that do being subtracted from it. that will leave the number of males that use their phone less than an hour a day, which is your answer.)
