Make 2 equations one for the price and one for quantity. so first set x = AA and y= AAA. for price 37= 1x+.75y. now for the quantity we have x+y=42. Now we can solve by subtracting the equation for price from the equation for quantity and we get .25y =5. solving this we get y= 20. Now we plug that value back in and solve for x. 22 double A's and 20 triple A's.

Answer:
You have 1.07 acres in this building lot and you can only build 2 houses.
Step-by-step explanation:
You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses.
We are given that 1 acre = 43,560 square feet.
In this building plot (260 foot by 180 foot), the area is:
260 * 180 = 46,800 square feet
Hence, the number of acres we have in this lot is:

Since your town requires 1/2 acre to build a house, the number of houses that you can build on it will be:

Since the number of houses can only be whole number, we approximate to nearest whole number ≅ 2 houses.
You have 1.07 acres in this building lot and you can only build 2 houses.
