For this case we can use the following rule of three:
 $ 500 ---------> 100%
 $ 400 ---------> x
 Clearing x we have:
 x = (400/500) * (100) = 80%
 Therefore, the percentage of decrease in the rent is:
 p = 100-x
 p = 100-80
 p = 80%
 Answer:
 
a proportion can be used to calculate p is:
 
p = 100 - ((400/500) * (100))

Tristen is building 3 trophies using Legos. He needs 324 total Legos. Tristen uses 220 Legos for the largest trophy and 135 Lego
Alexeev081 [22]

Answer: 166

Step-by-step explanation:

Number of trophies = 3

Total Legos required for all trophies = 324

Number of Legos for largest trophy(A) = 220

Number of Legos for smallest trophy(B) = 135

Number of Legos required for final trophy(C)

=?

Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]

324 = 220 +135 + C

324 = 355 + C

324 - 355 = C

-31 = C

135 + 31 = 166
