Answer: 300
We know that 5×3=15. Since we are trying to get 1500 we Multiply 300×5 and get 1500.
<u>How do we know?</u>
- As you can see if you cross out 2 of the 0 in 300 you have 3×5. When you multiply it you get 15.
- Also if you cross out 1 of the 0 in 300 you have 30×5. When you multiply that you get 150.
As you see when you still multiply either of those problems you have 15 in it. So we should know 300×5=1500.
Note: We can also multiply 500×3 and get 1500. You still get the same answer but just switched numbers.

choice 3) area = 1188 in²
Step-by-step explanation:
area = 36 x 33 = 1188 in ²
Let n be the 40%, and 100-n be the 10%. Then:
.4n+.1(100-n)=.22(100)
.3n+10=22
.3n=12
n=40
