Answer:
18.8888888889
Step-by-step explanation:
2 5/6 = 2.83333333333
6 2/3 = 6.66666666667
2 5/6 * 6 2/3 = 2.83333333333 * 6.66666666667
2.83333333333 * 6.66666666667= 18.8888888889
What We Know:
She can buy up to 8 boxes. Each box had 32 hot dogs. She can't buy partial boxes.
What We Need To FInd Out:
Practical Domain and Range.
On a graph, domain is the x value, (on the horizontal line,) and range is the y value, (on the vertical line.) She can buy 8 boxes. Practically, she wouldn't buy zero boxes of hot dogs, so it's 1-8. She has 15 hot dogs already, so add that to the first 32. 47-271.
So, if I'm correct...
Domain: 1-8
Range: 47-271
