Answer
Find out the ratio of price to pound for each bag.
To prove
As given
A store sells grass seed in small bags and large bags.the small bags have 7 pounds of seed for $27.93 .
7 pound = $27.93
Now find out the cost for the 1 pound.
[tex]1\ pound\ cost= \frac{27.93}{7}[/tex]
1 pound cost = $3.99
As given large bags cost $66.98.
Now find out pounds in the large bags.
Let us assume that the number of pounds in the large bags be x.
Than
3.99 × x = 66.98
[tex]x = \frac{66.98}{3.99}[/tex]
x = 16.8 pounds (approx)
Now find out the ratio of price to pound for each bag.
As small bags weight = 7 pounds
Cost of the small bags = $27.93
[tex]\frac{Price\ of\ small\ bag}{Cost\ of\ the\ small\ bags} = \frac{27.93}{7}[/tex]
As large bags weight = 16.8 pounds
Cost of the large bags = $66.98
[tex]\frac{Price\ of\ large\ bag}{Cost\ of\ the\ large\ bags} = \frac{66.98}{16.8}[/tex]
Hence proved
