Given:
y is proportional to x.
y=10 and x=8.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.

...(i)
Where, k is the constant of proportionality.
Putting y=10 and x=8, we get



Putting
in (i), we get

Therefore, the contestant of proportionality is
and the equation for the proportional relationship is
.
3 + 20x, where x= the number of hours bowled. A verbal diagram is where you say amount to pay per hour * number of hours + price of shoe rental = total cost.
