<h2>Answer:</h2>

The answer is:

  • 19, because the number of books is 95 over 4 divided by 5 over 4
<h2>Step-by-step explanation:</h2>

Samantha has a shelf that is 95 over 4 inches wide.

i.e. thickness of shelf=95/4 inches

Also, each book is 5 over 4 inches thick

This means that the thickness of one book is: 5/4 inches

Now,let n be the total number of books that could be arranged in the shelf.

This means that:

\text{Number\ of\ books\ arranged}=\dfrac{\text{Thickness\ of\ shelf}}{\text{Thickness\ of\ one\ book}}

i.e.

n=\dfrac{\dfrac{95}{4}}{\dfrac{5}{4}}\\\\i.e.\\\\n=\dfrac{95\times 4}{5\times 4}\\\\i.e.\\\\n=\dfrac{95}{5}\\\\i.e.\\n=19

Namely, how many times does 5/4 go into 95/4?   well, let's just divide,

\bf \cfrac{\quad \frac{95}{4}\quad }{\frac{5}{4}}\implies \cfrac{95}{\underline{4}}\cdot \cfrac{\underline{4}}{5}\implies \cfrac{95}{5}\implies 19

o-na [289]

Answer:

Cost for 68 words = 148 naira

Step-by-step explanation:

Given that:

Cost of first ten words = 32 naira

Cost of additional words = 2 naira per word

Let,

x be the number of additional words.

y be the total cost

y = 2x + 32

We have to find the cost for 68 words.

The cost of first 10 words will be 32 naira.

Additional words = 68 - 10 = 58 words

Putting x = 58 in the equation

y = 2(58) + 32

y = 116 + 32

y = 148

Hence,

Cost for 68 words = 148 naira
