In a new development, 50 one and two-bedroom condominiums were sold. Each one-bedroom condominium sold for $120 thousand and each two-bedroom condominium sold for $150 thousand. If sales totaled $7050 thousand, how many of each type of unit was sold?
Let no. of one bedrooms = x, then no. of two bedrooms = 50 - x.
Cost of x bedrooms @$120 = $120 x
Cost of 50 - x two bedrooms @$150 = $150(50 -x)
Now as per question,
So, no. of 1 bedrooms = 15 and no. of two bedrooms = 50 - 15 = 35.
In formula (
Subtract 6000 from both sides:
Conclusion : 15 one-bedroom and 35 two-bedroom.
