d+ t = 72
3t+t=72
4t = 72
t = 18

Answer:
6 ≤ x ≤ 12
Step-by-step explanation:
Instead of solving the area as 1.5*4x, you would do 6*x (multiply 1.5 by 4 and divide 4x by 4).
Then, you can just use division to find the answer.
36/6=6
72/6=12
And since 36≤A≤72, the area can be any number between 36 and 72, so x can be any number between 6 and 12.
The partial product of 4.6×3.5 is 16.1
Answer: <em>Multiply the original price by the decimal form of the percent and subtract that from the original price.
