Gavin wrote the equation [tex]p=\frac{3(s+100)}{4}[/tex] to represent [tex]p[/tex], the profit he makes from [tex]s[/tex] sales in his lawn-mowing business.

Which equation is solved for [tex]s[/tex]?

A. [tex]s=\frac{p-100}{3}[/tex]
B. [tex]s=\frac{4p-300}{3}[/tex]
C. [tex]s=\frac{4p}{300}[/tex]
D. [tex]s=\frac{400p}{3}[/tex]



Answer :

To solve for [tex]\( s \)[/tex] in the equation [tex]\( p = \frac{3(s + 100)}{4} \)[/tex], follow these steps:

1. Start with the given equation:
[tex]\[ p = \frac{3(s + 100)}{4} \][/tex]

2. Clear the fraction by multiplying both sides by 4 to eliminate the denominator on the right side:
[tex]\[ 4p = 3(s + 100) \][/tex]

3. Distribute the 3 on the right side:
[tex]\[ 4p = 3s + 300 \][/tex]

4. Isolate [tex]\( s \)[/tex] by getting all [tex]\( s \)[/tex]-terms on one side: Subtract 300 from both sides:
[tex]\[ 4p - 300 = 3s \][/tex]

5. Solve for [tex]\( s \)[/tex] by dividing both sides by 3:
[tex]\[ s = \frac{4p - 300}{3} \][/tex]

So, the equation solved for [tex]\( s \)[/tex] is:
[tex]\[ s = \frac{4p - 300}{3} \][/tex]

Among the given choices, the correct one is:
[tex]\[ s = \frac{4p - 300}{3} \][/tex]
