Answer:monthly rent of a 1-bedroom apartment= $280
Step-by-step explanation:
Let the cost of 1 bed room apartment = x
And the cost of two bedroom apartment= 2x-40
Since the cost of of two bedroom apartment = $520
Then the cost of one bed room part will be expressed as
520= 2x- 40
520+40 = 2x
560= 2x
x= 560/ 2
x= 280
Therefore the cost of 1 bed room apartment = x= $280
Answer:
C
note that (f - g)(x) = f(x) - g(x)
f(x) - g(x)
= 10x + 7 - (x² - 7x) ← distribute parenthesis by - 1
= 10x + 7 - x² + 7x ← collect like terms
= - x² + 17x + 7 → C
