Step-by-step explanation:
Since she starts with 37MB already download 37 will be a constant and for every second she is home she downloads 68 more MBs so to get the answers for the table you just have to do 37+ 68*(the number of seconds)
2=37+68(2)=173
4=37+68(4)=309
7=37+68(7)=513
9=37+68(9)=649
x = number of people went to movies
equation
6.25x + 12 = 30.75
6.25x = 30.75 - 12
6.25x = 18.75
x = 18.75 / 6.25
x = 3
answer
3 people
100 / 32 = 3.125
3.125 * 18 = 56.25.
