Answer:
Just multiply the number of weeks by 10
Step-by-step explanation
The current integer is 10/1 for 10 dollars made every 1 week.
So, if two weeks pass by, the integer will be 20/2 for 20 dollars made every
week.
If you continue this process by multiplying by 10, you'll get your chart.
That would just be a graph for y=-x. So ill give you a few points on it! (-2,2)(-1,1)(0,0)(1,-1)(2,-2) hope i helped!!!
If we need to find the total we can add everything that the store sold in those two hours
15+4+20+11 = 50
Therefore the ratio to produce to the total sold is
15:50
