In each case, divide the cost by the weight to find the cost per pound.
The unit rate is dollars per pound.
Sand a: $5/(60 lb) = 0.08333 $/lb
Sand b: $12/(150 lb) = 0.08 $/lb
A. Sand a is 0.08333 $/lb
B. Sand b is $0.08 $/lb
Sand b has a lower unit rate.
Sand b is is the better value.
If you buy the same amount of sand a and sand b, you will spend less money per pound of sand by buying sand b.

Answer: 5 minutes
Step-by-step explanation:
Answer:
x = 20 * s / 300
Step-by-step explanation:
In this case, it is solved by means of a rule of three, that is, we know that 20 of 300 answered yes, but in the case of the strata sample, since it is a value that is not mentioned in the problem, we will assume it as " s "and the people who were selected as" x ". would:
20 x
300 s
Therefore, x:
x = 20 * s / 300
and thus they would give us the number of people that would be selected.
For example, if "s" were 240, it would be:
x = 20 * 240/300
x = 16
that is, 16 people would be selected
