Answer:
Step-by-step explanation:
The statement "H(28) = 75.12 can be interpreted to mean that the average cost of cooling a house for" 28 days is $75.12.
Step-by-step explanation:
The given function H(d) = 1.54d + 32 represents the average cost of cooling a house in dollars, where d is the number of days the air conditioner is running. By substituting d = 28 into the function, we can calculate the average cost for cooling a house for 28 days.
H(28) = 1.54 * 28 + 32
= 42.12 + 32
= 74.12
Therefore, H(28) = 75.12 means that the average cost of cooling a house for 28 days is $75.12.
