Answer:
- The diagram bar is attached.
- Addition equation: 
- Multiplication equation: 
- How are the equation related? Each equation shows 3 groups of 7.
Step-by-step explanation:
We know that Jan buys 3 bags of beads and each bag contains 7 beads, then, you can draw the bar diagram shown attached.
Observe that the diagram has 3 blocks (each block represents a bag of bead) and there is a number 7 inside of each block (which is the number of beads contained in a bag).
Therefore:
- Add the numbers inside the blocks in order to get the addition equation that shows the number of beads Jan buys. This is:

- Multiply 3 blocks by 7 in order to get multiplication equation that show the number of beads Jan buys:

The equations are related. Each one shows 3 groups of 7.
Two points I can assuming to have integer coordinates (points without decimals in (x, y) ) are (0, 0) and (5, 40)
From this, I can make a safe assumption that y is 8 times the x value.
since x value is money spent on advertising in $1000s', number of vehicles is 80 times of how much money is spent on advertising in $1000.
But, if you want to be fancy (or I guess this is more correct), 8/1000 = 0.08, so for extra dollar spent, 0.08 more vehicles are sold, rounded down.
