Weight = 1 1/4
convert to simple fraction= 5/4 pounds
The cost of 5/4 pounds of package = $9
Let us find the cost per pound
cost per pound = 9/5/4
multiply by the multiplicative inverse of the denominator
cost per pound = 9*4/5
cost per pound = 36/5
cost per pound = $7.2 per pound
Hence the cost of 1 pound of the package is $7.2
