8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
Answer:
2 → 3 → 1 → 4
Step-by-step explanation:
We are given the list of cost of fabric in dollars per square yard.
So, the total cost per square yard of different fabric are:
1. 6.5 for $6.25 =
= 0.96
2. 4 for $3 =
= 0.75
3. 8.5 for $8.10 =
= 0.95
4. 6 for $7.20 =
= 1.2
Since, 0.75 < 0.95 < 0.96 < 1.2
Hence, from least to the greatest unit cost, the sequence is 2 → 3 → 1 → 4.
