Liono4ka [1.6K]

Answer:

His book was opened at Page no.296 and Page no.297

Step-by-step explanation:

Let the page number of one page be x

Page number of page facing page no. x = x+1

We are given that the product of the facing pages was 87,912.

So, x(x+1)=87912

x^2+x=87912

x^2+x-87912=0

x^2-296x+297x-87912=0

x(x-296)+297(x-296)=0

(x+297)(x-296)=0

x=296,-297

Since Page no. cannot be negative

So, x=296

x+1=296+1=297

So, his book was opened at Page no.296 and Page no.297

velikii [3]

Step 1: Let's review the information provided to us to answer the problem correctly:

• Option 1: $5.99 for 12 coffees

,

• Option 2: $ 23.99 for 70 coffee

Step 2: Let's calculate the cost of a coffee in each option, as follows:

• Cost of a coffee in Option 1 = 5.99/12 = 0.50 (rounding to the next cent): This means that every cup of coffee costs $ 0.50

• Cost of a coffe in Option 2 = 23.99/70 = 0.34 This means that every cup of coffee costs $ 0.34

Step 3: Now we can decide which is the better deal and why.

The better deal is option ........ because it is cheaper than option..........

You can complete step 3, Kay.
