Total units would be: 3+4 = 7
value of 1 unit = 28/7 = 4
ratio would be 3(4) & 4(4) = 12 & 16
The independent variable is the cost of the skateboard, c.
The dependent variable would be the total cost, t.
The best way to understand this is that the cost of the skateboard from the company is not going to change based on a sales tax rate., But the overall total cost could change depending on what the sales tax rates are.
The total cost would be dependent upon the sales tax rate.
Answer:
im pretty sure its B, i hope it helps
Step-by-step explanation:
Just go ahead and subtract 3/4x and bring it to the other side so it should look like this -2y=5-3/4x then go ahead and divide with negative two
Subtract 4x on both sides then divide by negative to all three numbers and your answer will be y = 1/2x - 3/2
