Question

The Spanish club held a car wash to raise money. The equation y=5x represents the amount of money y club members made for washing x cars. Identify the constant of proportionality. Then explain what it represents in this situation.

Answer 1

the constant of proportionality is x=y/5 because its the constant that is not changing in he proportion. It represents the total of members made for washing x cars.

Answer 2

Answer:

The constant or proportionality is 5 and it represents the cost of washing per car.

Step-by-step explanation:

Given equation that represents the price of washing of x cars,

y = 5x -----(1)

∵ by the above equation with increasing x, y increases directly,

⇒ y is directly proportional to x,

That is, y ∝ x ------(2),

By comparing equation (1) and (2),

5 is the constant or proportionality,

If x = 1, y = 5

Thus, the price of washing per car is 5.
