Question

За ручку и набор фломастеров заплатили 48 руб. Набор фломастеров в 5 раз дороже ручки. Сколько стоит ручка? сколько стоит набор фломастеров? Сколько нужно заплатить за 10 таких ручек? за 3 таких набора фломастеров?

Answer 1

Ручка стомт х руб. фломастеры 5х руб.
1) х+5х=48
6х=48
х=48:6
х=8 руб. стоит ручка.
8×5=40 руб. чтоят фломастеры.
10×8=80 руб. стоят 10 ручек.
40×3=120 руб. стоят 3набора фломастеров.

Answer 2

1) 48:(1+5)=8(рублей)-стоит ручка.
2)8*5=40(рублей)-стоит набор.
3)8*10=80(рублей)-стоят десять ручек.
4)40*3=120(рублей)-стоят три набора.
Как-то так.

Answer 3

Calculation of the Cost of a Pen and a Set of Markers

To calculate the cost of a pen and a set of markers, we are given the following information:

- The total cost of a pen and a set of markers is 48 rubles. - The set of markers is 5 times more expensive than the pen.

Let's denote the cost of the pen as P and the cost of the set of markers as M.

From the given information, we can set up the following equations:

1. P + M = 48 (equation 1) 2. M = 5P (equation 2)

To find the cost of the pen and the set of markers, we need to solve these equations simultaneously.

Solving the Equations

Substituting equation 2 into equation 1, we get:

P + 5P = 48

Simplifying the equation:

6P = 48

Dividing both sides by 6:

P = 8

Now that we have the cost of the pen, we can substitute this value back into equation 2 to find the cost of the set of markers:

M = 5P = 5 * 8 = 40

Therefore, the cost of the pen is 8 rubles and the cost of the set of markers is 40 rubles.

Calculation for 10 Pens and 3 Sets of Markers

To calculate the cost of 10 pens, we multiply the cost of one pen by 10:

10 * 8 = 80 rubles

To calculate the cost of 3 sets of markers, we multiply the cost of one set of markers by 3:

3 * 40 = 120 rubles

Therefore, the cost for 10 pens would be 80 rubles and the cost for 3 sets of markers would be 120 rubles.
