Answer:
The cost of 1 note book = Rs 43.5
Step-by-step explanation:
Given in question as :
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 pen (P) + 1 (N) total cost = Rs 81
So, from above equation
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 × 95 pen (P) + 1× 95 notebook (N) total cost = Rs 81 × 95
Or, (95 pens (P) + 95 notebook (N) ) - (95 pens (P) + 89 notebook (N) ) = (7695 - 7434)
Or , 6 N = Rs 261
Or, N =
= Rs 43.5
Hence the cost of 1 notebook is Rs 43.5 Answer
Answer:
The answer is simply 26,25/3 which gives that each book costed 8,75 dollars assuming of course that all books have the same price.
Answer:
Hence after solving the given equation we get <em>x = 13/20.</em>
Step-by-step explanation:
<em>Given:</em>
<em>-3 x + 0.1 + 10 x = x + 4</em>
<em>-3 x + 10 x - x = 4 - 0.1</em>
<em>6 x = 3.9</em>
<em> x = 
</em>
<em>x = 
</em>
<em>x = 
</em>
Answer:
8/2
Step-by-step explanation:
