50 km/h = 4 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours
The correct answer is 3,520 people purchase something. Explanation: 4/10 = .4, so 8,880 x .4 = 3,520
You multiply both of the equations until you have two of the same term the same like for example, say I have 4x and 5x. You want to multiply until both have the same number, so multiply 5x by four, then multiply 4x by five, and you will get 20x, then both of those cancel out and you will be left with the other variable, and you just solve like a normal equation.
The range is all positive values...
R{y | y>0}
Range > "Y" such that y is greater than 0
