A contractor is hired to construct two concrete retaining walls for the city: Harrison Wall and Jackson Wall. As part of his budget, he needs to calculate the cost of the concrete he will use. For raw materials for the concrete, he has to pay $9.75 per cubic meter of concrete. Harrison Wall will be 35 cm thick, and will have dimensions of 11.5 m long and 8.1 m high. Jackson Wall will be 50 cm thick, and will have dimensions of 31.0 meter long 11.8 m high.
In the table, select the value that the closest to the cost of the concrete for Harrison Wall as well as the cost of the concrete for Jackson Wall. Make only two selections, one in each column.

Volume of Harrison Wall = 0.35 * 11.5 * 8.1 \(m^3\)
Volume of Jackson Wall = 0.5 * 31 * 11.8 \(m^3\)
Cost of 1 \(m^3\) of concrete = $9.75
Therefore, Cost of Harrison = 0.35 * 11.5 * 8.1 * 9.75 ~ $320
Cost of Jackson = 0.5 * 31 * 11.8 * 9.75 ~ $1800.
