Question

В одном рулоне 12 метров ткани а во втором 17 метров такой же ткани второй рулон стоит на 3.750 тенге дороже Сколько надо заплатить за каждый рулон

Answer 1

17-12=5 метров больше
3,75:5=0,75 тенге стоит 1 м ткани
12*0,75=9 тенге стоит 1-й рулон
17*0,75=12,75 тенге стоит 2-й рулон

Answer 2

Calculating the Cost of Each Roll of Fabric

To calculate the cost of each roll of fabric, we can use the information provided.

Let's denote the cost of the first roll of fabric as x (in tenge). The cost of the second roll of fabric would then be x + 3750 (in tenge), as it is stated to be 3750 tenge more expensive.

Given that the first roll is 12 meters and the second roll is 17 meters of the same fabric, we can set up a proportion to find the cost per meter of fabric.

Setting Up the Proportion

We can use the following proportion to find the cost per meter of fabric:

12 meters of fabric costs x tenge 17 meters of fabric costs (x + 3750) tenge

Solving the Proportion

To solve for x, we can cross-multiply and solve for x:

12(x + 3750) = 17x

Calculating the Cost

Let's solve for x to find the cost of the first roll of fabric.
