Answer:
Compare the cost for the each (smallest) unit.
Step-by-step explanation:
You can calculate the cost per unit
For example :
20 ounces of water of brand A cost 1.50
30 ounces of water of brand A cost 2
20 ounces of water cost 1.50/20 = 0.075 dollar per ounce
30 ounces of water cost 2/30 = 0.0677 dollar per ounce
We can wrap 12 presents. multiply the number of yards by the feet.
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k = 
= 
= 
, thus
y = x ← equation of variation
When x = 18, then
y = × 18 = 
= 6
Answer:
Step-by-step explanation:
