Suppose a food has 300 cal per serving. what is the maximum number of grams of fat that the food contain in order for the percent of calories from the fat to be 40% or less?

I don't really know I just need points

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
