Answer:
the first option
Step-by-step explanation:
it is directly there in the problem description.
f(x) = 1.8x - 10
g(x) = -4
so, for f(x)=g(x) that automatically means
1.8x - 10 = -4
1.8x = 6
x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3
We have two equations
One to for the total number of units, to distinct them from 1 bedroom units or 2 bedroom units
x- one bedroom units
y- two bedroom units
x+y= 100
495x+600y= 55,275
We can try to plug in these values for y since it’s asks “how many two bedroom apartments are there” and see if it works out
495x+600(45)= 55,275
495x+27000=55275
-27000 -27000
495x= 28275
/495 /495
x=57.12
There can’t be 57.12 units so A is wrong
495x+600(55)= 55,275
495x+ 33000= 55275
-33000 -33000
495x =22275
/495 /495
x=45
This could work so B is the answer , you could go ahead and try C and B but most likely the answer is B
