Question

the formula $p = c + m$ can be used to determine price $p$ of an item that costs $c$ cents and a markup of $m$ cents. what is an equivalent version of this formula solved for $c$?
options:

• $c = 25p$
• $c = p - 25$
• $c = \frac{p}{25}$
• $c = p + 25$

Explanation:

Step1: Start with given formula

$P = c + m$

Step2: Isolate $c$ by subtracting $m$

$c = P - m$
(Note: Based on the options provided, it appears there is a typo in the original problem, and the markup value is 25 cents. Using this assumption to match the options)

Step3: Substitute $m=25$

$c = P - 25$

Answer:

$\boldsymbol{c = P - 25}$ (matches the second option: $\boldsymbol{c=P-25}$)
