MSTC Refresher 105: Converting a Table to Matrix Form

Suppose the purchase prices and delivery costs (per unit) for wood, siding, and roofing used in construction are given in the table. Then the table of unit costs may be represented by the matrix 𝐶.
WOOD
SLIDING
ROOFING PURCHASE 6 4 2
DELIVERY
1
1
0.5
𝐶=[642110.5]
If the supplier announces a 10% increase on both purchase and delivery of these items, find the new unit cost matrix.
A. 𝐶=[6.654.452.201.101.100.56]
B. 𝐶=[6.604.402.201.101.100.60]
C. 𝐶=[6.604.402.201.101.100.55]
D. 𝐶=[6.654.452.251.101.100.55]
