Answer:
P=x/2.2
Step-by-step explanation:
We can set up an equation to solve this.
Let P represent the number of pounds
Let X represent the number of kilograms
Knowing that 1 kilogram equals 2.2 pounds.
So, if there is 1 kilogram (X) it translates to 2.2 pounds (P).
X=2.2P
Simply rearrange the equation to determine the pounds in x kilograms. Thus, divide both sides by 2.2.
Therefore, we derive P=x/2.2
Answer:
$110.
Step-by-step explanation:
Let x represent the cost of the item that Carmen bought from the department store.
Carmen possesses $30 in store bucks along with a 25% discount coupon for a local department store. Our goal is to determine the maximum cost for Carmen's purchase such that after applying her store bucks and discount, her total remains at or below $60 before sales tax.
Since the $30 in store bucks is deducted prior to applying the 25% discount, we need to find x such that x - 30 minus 25% of (x - 30) must be less than or equal to 60. This can be set up as an equation:

Thus, Carmen's purchases should total no more than $110 before sales tax.
To tackle this, we can utilize ratios. For instance, 4 1/2 kg of olive oil costs $27. Therefore, the price for 1 kg of olive oil can be represented as follows: x = (27 * 1) / 4.5 which simplifies to x = 27/4.5. This calculation results in a cost of $6 per kilogram. Hope this is of assistance!
