Is there a mistake here

(0) == | o | meaning the cost of buying | 0 | gallons of lemonade would be $ 0.00 | This interpretation makes sense i y in the context of the problem. f(85) = 73.76 | meaning the cost of buying gallons of lemonade would be $| 73.76 |. This interpretation makes sense in the context of the problem. f (62.5) = | 63.28 | meaning the cost of buying 62,5 gallons of lemonade would be $ 63.28 |. This interpretation makes sense in the context of the problem. Based on the observations above, it is clear that an appropriate domain for the function is non-negative real numbers ~
