A:
Answer:see explanation belowStep-by-step explanation:In order to do this, you can put and solve this in this way:we know that the ratio between chips and water is 4:3 so:Chips/Water = 4/3Solving for chips:Chips = 4 Water / 3Now put the price of the water here, and you should get the price of the chips:Chips = 4 * 1.8 / 3Chips = 2.4 $b) If the chips cost 2.4 and the drink 1.8, the total is 4.2, therefore, the total amount is:4.2/6 = 2.1/3 = 0.7/1c) If 6$ is 37.5% then the 100% would be:6 * 100 / 37.5 = 16$
