The price of a book is thrice that of an exercise book. of a student spend #9600 on book and #8000 on exercise book, he has 56 i

poizon [28]

Answer:

a) price of an exercise book = #200

b) #400

Explanation:

Let x represent the price of the book

Let y represent the price of the exercise book

- According to this question, the price of the book is thrice that of an exercise book i.e. x = 3y

- Also, the question states that if a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether. This means that to get how many books and exercise books he bought, we divide the price of book and exercise book he bought by the price of each book (x) and exercise book (y) respectively. Mathematically, this means:

- Student bought 9600/x books

- Student bought 8000/y exercise books

So, 9600/x books + 8000/y exercise books = 56 item

9600/x + 8000/y = 56

Since x = 3y

We can say;

9600/3y + 8000/y = 56

Find the L.C.M of 3y and y = 3y and solve using fraction method (see attachment).

9600 + 24000/3y = 56

33600/3y = 56

Cross multiply

33600 = 56 × 3y

33600 = 168y

Divide both sides by 168

33600/168 = 168y/168

200 = y

y = 200

Since, x = 3y

x = 3 × 200

x = 600

Therefore, the price of book (x) and exercise book (y) are #600 and #200 respectively.

b) The difference between the price of a book and an exercise book i.e. x - y

= #600 - #200

= #400

EastWind [94]

Rods and cones are similar in that they both release glutamate as the primary neurotransmitter. During signalling the rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter glutamate to bipolar cells at its axon terminal. Every rod and cone photoreceptor release the same neurotransmitter, glutamate.
