Each pair of pants at a store costs [tex]\$45[/tex]. If the equation [tex]45p = 270[/tex] represents the total amount of money that a shopper spent on pants, which of the following best interprets what [tex]p[/tex] represents?

A. The cost of each pair of pants the shopper purchased
B. The number of days the shopper purchased pants
C. The total number of pairs of pants the shopper purchased
D. The cost of one pair of pants that the shopper purchased



Answer :

To determine what [tex]\( p \)[/tex] represents in the equation [tex]\( 45p = 270 \)[/tex], let's break down the problem step by step.

1. Understand the Given Equation:
The equation is [tex]\( 45p = 270 \)[/tex]. Here, [tex]\( 45 \)[/tex] represents the cost of one pair of pants in dollars, and [tex]\( 270 \)[/tex] represents the total amount of money spent by the shopper.

2. Rewriting the Equation:
The equation can be interpreted as:
[tex]\[ \text{cost per pant} \times \text{number of pairs of pants} = \text{total amount spent} \][/tex]
In this case, the cost per pant is [tex]\( \$45 \)[/tex], and the total amount spent is [tex]\( \$270 \)[/tex].

3. Solve for [tex]\( p \)[/tex]:
To find [tex]\( p \)[/tex], we need to isolate [tex]\( p \)[/tex] on one side of the equation.
[tex]\[ 45p = 270 \][/tex]
Divide both sides of the equation by [tex]\( 45 \)[/tex] to solve for [tex]\( p \)[/tex]:
[tex]\[ p = \frac{270}{45} \][/tex]
Simplifying the division:
[tex]\[ p = 6 \][/tex]

4. Interpret [tex]\( p \)[/tex]:
From the equation solving process, we deduced that [tex]\( p \)[/tex] is [tex]\( 6 \)[/tex]. Since [tex]\( 45p \)[/tex] represents the total amount spent, [tex]\( p \)[/tex] equals the number of pairs of pants purchased.

Thus, [tex]\( p \)[/tex] represents the total number of pairs of pants the shopper purchased.

So, the correct interpretation is:
- The total number of pairs of pants the shopper purchased
