Answer:
(an open) (30) (greater than 30) ( 40)
Step-by-step explanation:
I did the assignment on Edge 2020
draw (an open) circle at (30) shade all numbers (greater than 30) check the graph of the solution by substituting (40) in for the variable .
Swimmers: 50 children ÷ 12 = 4.2 (you can't have a decimal so you must round up)
5 adults are need.
Dancers: 32 children ÷ 15 = 2.1 (you can't have a decimal so you must round up)
3 adults are need.
Minimum number of adults needed is: 5 for swimmers + 3 for dancers = 8 adults
60minutes because 24 divide 8 is 3 and 3 times 20 is 60
