Answer:
Its 3.5c
Step-by-step explanation:
Let's find the constant of proportionality.
In the proportional relationship between c, the number of cranes, and t, the total time in minutes, one constant of proportionality is the amount of time per crane. It is the number we multiply by the number of cranes to get the total time.
c times ? =t
The constant of proportionality is 3.5 This means we can multiply 3.5 by the number of cranes to get the total time.
Now, let's represent that as an equation.
total time= time per crane X number of cranes
total time
t
time per crane×number of cranes
3.5c
One correct equation is:
t= 3.5c
