Answer:
1. $560
Explanation:
Since the length and width are given in ft and in., first, we will conver the dimensions to inches. 1 ft = 12 in.
area of the room:
A = (11 ft 10 in.) × (14 ft 9 in.)
A = 142 in. × 177 in.
A = 25,134 in.²
1 yd = 36 in.
Now we convert the area into yd².
A = 25,134 in.² × (1 yd²)/(36 in.)²
A = 19.3935 yd²
The cheapest carpet costs $19.95/yd².
Add the cost of removal and installation of new pad: $19.95/yd² + $6.89/yd² = $26.84/yd².
The most expensive carpet costs $22.95/yd².
Add the cost of removal and installation of new pad: $22.95/yd² + $6.89/yd² = $29.84/yd².
The range of prices per square yard is from $26.84/yd² to 29.85/yd².
The cheapest carpet will cost:
19.3935 yd² × 26.84/yd² = $520.52
The most expensive carpet will cost:
19.3935 yd² × 29.84/yd² = $578.70
The price is between $520.52 and $578.70.
Choices 2. $650 and 4. $480 are eliminated.
She is not using the most expensive carpet, so it will cost less than $578.70, so choice 3. $580 is eliminated.
