Question

07.) If 4z books cost of (8z² +5z) what is the cost of one book? ​

Answer 1

Answer:

If the cost of 4z books is $8z^{2} +5z$, then the cost of 1 book is $\frac{8z+5}{4}$

Step-by-step explanation:

Given

Cost of 4z books = $8z^{2} +5z$

So, cost of 1 book =

$\frac{8z^{2} +5z}{4z}\\\\= \frac{z( 8z+5)}{4z} \\\\= \frac{8z+5}{4}$

So the cost of one book is $\frac{8z+5}{4}$
