To convert 7 yards per month to inches per year, we first need to know the conversions between the different units involved.
1 yard = 36 inches. 1 year = 12 months.
Now we can calculate the equivalent rate:
-
Convert yards to inches: \[ 7 \text{ yards} = 7 \times 36 \text{ inches} = 252 \text{ inches} \]
-
Since this is a monthly rate, we now find the annual rate by multiplying by the number of months in a year: \[ 252 \text{ inches/month} \times 12 \text{ months/year} = 3024 \text{ inches/year} \]
Thus, the equivalent rate is: \[ \boxed{3024} \text{ inches/year} \]
