Identify the original monthly cost and the percentage increase. Here, the original cost is \$54 and the increase is 8%.
Convert the percentage increase to a decimal by dividing by 100: 8\% becomes 0.08.
Calculate the amount of the increase by multiplying the original cost by the decimal increase: \(54 \times 0.08\).
Add the increase amount to the original cost to find the new monthly cost: \(54 + (54 \times 0.08)\).
Express the final answer as the new monthly cost after the increase.
