Lizzy has to ship 540 pounds of fish that are packed into 30-pound crates. If the shipping cost of each crate is $1.5, how much will Lizzy pay for the shipment?
assistant
How many crates of fish are needed? ** There are 540 pounds / 30 pounds/crate = <<540/30=18>>18 crates of fish needed.
How much will Lizzy pay for the shipment? ** Hence, the total cost for the shipment is $1.5/crate x 18 crates = $<<1.5*18=27>>27.
