Question

Mana is saving to buy a new bicycle. The equation d = 12w represents the amount in dollars, d, that Mana saves in w weeks.What is the constant of proportionality? What does it represent in this situation?

Answer 1

Constant of proportionality is 12

The cost of buying new bicycle changes 12 dollar per week

Explanation:

we are given

The equation as

`d=12w`

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

`y=kx`

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

`12=(d)/(w)`

So,

The cost of buying new bicycle changes 12 dollar per week
