Answer:
$15.40
Step-by-step explanation:
Total length of wood required: 21 ft
Cost per yard: $2.20 per yard.
3 ft = 1 yard.
Therefore, total length of wood required = 21/3 = 7ft
Thus, the total cost she would spend on the wood is:
Cost to buy a single yard's length of wood * The length of the boarder
=> 2.20 * 7 = $15.40
