<u>Answer:</u>
A ski resort makes snow fan. The expression is 7200 + 57d
<u>Solution:</u>
Given, A ski resort makes snow fan that costs $1200.
The fan has an average daily operation cot of $9.50.
We have to write a simplified expression that represents the cost to purchase and operate 6 snow fans.
And variable d represents the number of days that the resort operates the fans.
Now, <em>cost of 6 snow fans </em>= 6 x cost of each snow fan = 6 x 1200 = 7200
And, <em>cost to operate 6 fans</em> = 6 x number of days x cost to operate each fan = 6 x d x 9.5 = 57d.
So, the expression for<em> total cost will be cost of fans + cost to operate</em> = 7200 + 57d.
Hence, the expression is 7200 + 57d.
