Answer:

a decrease of 80%

Explanation:

Mr. Lui had lunch, he began with 50$ and came out with 10$

With that we would use the Percentage change equation

PC= 1.00- (amount left/total amount)

(PC means percentage change)

PC= 1.00- (10/50)

we can reduce 10/50 to 1/5 by reducing by 5

PC= 1.00 -(⅕)

now we would change the fraction to a decimal by dividing

5÷1= .20

PC= 1.00 - .20

PC=.80

move the decimal place twice to the right

80%
