Tim wants air conditioning in his room. The air conditioner costs $40. Each day the electricity costs $1. Write an expression that can be used to find the total cost to run the air conditioner for \( d \) days.

Answer :

The total cost to run the air conditioner for d days is given by the expression $40 + $1d, considering the initial purchase cost and the daily electricity cost.

To calculate the total cost of running an air conditioner for d days, we need to consider both the initial cost of the air conditioner and the daily cost of electricity. The initial cost of the air conditioner is a one-time cost of $40. The daily cost of electricity is $1 per day. Therefore, the expression would be the initial cost plus the daily cost multiplied by the number of days d.

The expression can be written as follows:

Total Cost = Initial Cost + (Daily Electricity Cost * Number of Days)

Total Cost = $40 + ($1 * d)

So, the expression to find the total cost for d days would be $40 + $1d.

Answer:

the answer/expression you require is 40 - 1 = 1 day x - 1 = day 2 (repeat day 2 forever

Step-by-step explanation:

i say this because - 40 for the air conditioner and if it’s - 1 for electricity a day then unless your buying an air conditioner every day i don’t think you,l be repeating day 1 every day
