A sports drink is advertised as 20 fluid ounces, but the amount varies by 0.45 fluid ounces. If x represents the amount of ounces in each sports drink, write an equation to model the maximum and minimum amounts and determine the minimum amount for the drink.
|x − 0.45| = 20; x = 19.55 ounces
|x + 0.45| = 20; x = 20.45 ounces
|x − 20| = 0.45; x = 19.55 ounces
|x + 20| = 0.45; x = 20.45 ounces
1 answer
The minimum amount for the sports drink is 19.55 ounces.
