Answer:
the total cost of the brackets before tax is $89.7
Step-by-step explanation:
The computation of the total cost of the bracket before tax is as follows
Given that
height = 9 feet
length = 10 feet
wall brackets:
48-in costing $12.95
60-in costing $16.95
The distance of brackets from ends is 1 foot
The maximum distance between brackets is 24 inches
Now based on the above information
The brackets are
= 48 ÷ 12
= 4 feet
And
= 60 ÷ 12
= 5 feet
The length of the shelf is 60 inch
Now the 1 could be deducted from each side
= 60 - 2
= 58 in
Now Divide it by 24 inches
= 58 ÷ 24
= 2.41 ~ 3
Finally, The total cost is
= ($12.95 + $16.95) × 3
= $89.7
Hence, the total cost of the brackets before tax is $89.7
