Answer:

$\frac{25}{4}$

Cereal costs 2.79 for 16.4 ounces. At this rate how much does 25 ounces of cereal cost? Round to the Nearest Cent.

ankoles [38]

Answer:

$4.25

Step-by-step explanation:

We can create a proportion to find how much 25 oz will cost:

$\frac{2.79}{16.4}$ = $\frac{x}{25}$

We can cross multiply to find x.

16.4x = 69.75

x = 4.25

So, this means 25 ounces of cereal will be $4.25

The shop declare a discount of 20% and later a discount of 15% after

Oksi-84 [34.3K]

In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68

So, Total discount would be: 100 - 68 = 32%

Hope this helps!
