Answer:
Suppose a crew at an unloading dock can unload 3 trucks per hour and have already unloaded 17 trucks. Which equation can be used to model the number of trucks the crew unloads after h hours?
A. y = 3h = 17
B. y = 3h + 17
C. y = 17h – 3
D. y = 17h + 3
Step-by-step explanation:
The equation that can be used to model the number of trucks the crew unloads after h hours is y = 3h + 17.
Given:
A crew can unload 3 trucks per hour.
A crew unloaded 17 trucks.
Let the total number of trucks unloaded by the crew after h hours be y.
Trucks unloaded after h hours = 3h
Already 17 trucks has been unloaded.
The total trucks unloaded after h hours is:
⇒ y = Trucks unloaded after h hours + 17
⇒ y = 3h + 17
Therefore, the equation that can be used to model the number of trucks the crew unloads after h hours is y = 3h + 17.
Hence, option (D) is correct.
