To find the mean amount of the cable bill for the year, calculate the total cost for the year and then divide by 12 (the number of months). For the first 5 months, the cost was $5 \times \$26.89 = \$134.45$. For the next 7 months, the cost was $7 \times \$28.89 = \$202.23$. The total cost for the year is $\$134.45 + \$202.23 = \$336.68$. The mean monthly cost is $\$336.68 / 12 = \$28.06$.
