The equation t = 0.07c represents the tax, t, based on the cost, c, of an item. Which part of the equation represents the constant of proportionality?

Verified Answer :

You just told us that 't' is the tax, and 'c' is the cost of the item.

We know it's not the 'equals' sign (=), so the only thing left
that it could be is the 0.07 .

Answer:

Hence, the part of equation that represents the constant of proportionality is:

0.07

Step-by-step explanation:

We are given a equation in terms of variable t and c as:

\(t=0.07c\)

where t is the tax based on the cost, c of an item.

The constant of proportionality is the ratio between two directly proportional quantities.

Here the two quantities are t and c.

Also,

\(\dfrac{t}{c}=0.07\)

Hence, from the definition of constant of proportionality we observe that the part of the equation that represents the constant of proportionality is:

0.07
