Question

Gavin wrote the equation p = StartFraction 3 (s + 100) Over 4 EndFraction to represent p, the profit he makes from s sales in his lawn-mowing business. Which equation is solved for s? s = StartFraction p minus 100 Over 3 EndFraction s = StartFraction 4 p minus 300 Over 3 EndFraction s = StartFraction 4 p Over 300 EndFraction s = StartFraction 400 p Over 3 EndFraction

Answer 1

the answer is b

Explanation:

Answer 2

Given the equation p = 3(s + 100)/4

Where,

p = profit made

s = sales

Solving for s from the given equation

p = 3(s + 100)/4

Multiply both sides by 4

4p = 3(s + 100)

4p = 3s + 300

Subtract 300 from both sides of the equation

4p – 300 = 3s

Same as, 3s = 4p – 300

s = (4p – 300)/3

OR, s = 4p/3 – 100

If any of these two is in the options, it’s the right answer.
