Check Explanation
Step-by-step explanation:
The volume of concrete required to build the bridge is missing and should be provided.
In its absence, let us assign a letter to it.
Let the volume of concrete required to build the bridge be V ft³.
And we further assume that the concrete is the only major material needed to build the bridge for the sake of our question.
Density = (mass/volume)
Density = 150 lb/ft³
Mass = ?
Volume = V ft³
Mass = (Density) × (Volume)
Mass of concrete required = 150 × V = (150V) lb
Cost of concrete is 0.80 per lb
1 lb of concrete costs 0.80
150V of concrete will cost 150V × 0.80 = (120V) currency amount.
Now, depending on the value of V, we can now determine if the city planning commission (cpc) can afford the bridge.
If 120V > 300,000 budget, the cpc cannot afford the bridge, but if 300,000 budget > 120V, then the cpc can afford the bridge.
Hope this Helps!!!
