Answer:
x = 112
Step-by-step explanation:
= ( cross- multiply )
3x = 7 × 48 = 336 ( divide both sides by 3 )
x = 112
Answer:
p(x) = 8x - 20
Step-by-step explanation:
revenue from selling x shirts is f(x) = 15x
The cost of buying x shirts is c(x) = 7x + 20
p(x) = f(x) - c(x)
To solve this, we need to substitute value of f(x) and c(x) in formula for p(x)
p(x) = f(x) - c(x)
p(x) = 15x -( 7x + 20)
=> p(x) = 15x - 7x -20
=> p(x) = 8x -20
Thus, profit is p(x) = 8x - 20.
