• In order to get the resulting average of the 11 brands, let us first multiply 254 by 9 since that's the average of the 9 brands.
> Thus, we have the approximate sum of the first nine bags.
• Let's now get the resulting average by adding 2,286 with the price of the two other brands then divide the answer by 11, total number of brands.
> Therefore, the resulting average of the 11 brands is Php. 260.00
• You are tasked to find the distance travelled by the car per liter of gasoline.
• Try to apply what you've learned from the lesson in ratio and proportion.
> On a liter of gasoline, his car can cover 14.62 kilometers.
