It's 64 because 38 plus 28 gives you 64
Answer:
Domain { 4,8,12,16,20}
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
Step-by-step explanation:
The domain is the x values ( input)
Domain { 4,8,12,16,20}
The range is the y values (output)
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
The equation is 70 35
----- = ------
100 x
To solve, multiply diagonally
You should get 70x = 3500
Then to get x alone, divide each side by 70
Your answer should be 50
You would take answer you got for how much they spent and multiply the answer by 2.
