400
Step-by-step explanation:
Percentage decrease = 20% × 500
New value = 500 - Percentage decrease
500 - (20% × 500) =
500 - 20% × 500 =
(1 - 20%) × 500 =
(100% - 20%) × 500 =
80% × 500 =
80 ÷ 100 × 500 =
80 × 500 ÷ 100 =
40,000 ÷ 100 =
400
The first problem Levi solves is incorrect, because 5/4 is not equal to 20.
The second problem Levi solves is correct, because 1.5 x 10 is 15, which subtracting 8 is equal to 7.
The third problem Levi solves is correct, because 4 x 13 is 52 and plus 6 it is 58.
I hope this helps!
