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

There are 55 two-bedroom units  in the apartment.

Let x represent the number of one bedroom units and y represent the number of two bedroom units.

Since the apartment building contains 100 units, hence:

x + y = 100      (1)

The total monthly rent paid by the tenants is $55,275, hence:

495x + 600y = 55275   (2)

Solving equation 1 and 2 simultaneously gives:

x = 45, y = 55

Hence, there are 55 two-bedroom units  in the apartment.
