Answer 3

Problem Analysis

To solve this problem, we need to determine the number of coats that can be made from each piece of fabric. We are given two pieces of fabric, one measuring 96 meters and the other measuring 84 meters. From the information provided, we know that the number of coats made from the second piece is 3 less than the number of coats made from the first piece.

Solution

Let's assume that the number of coats made from the first piece of fabric is x. Therefore, the number of coats made from the second piece of fabric would be x - 3.

To find the number of coats made from each piece, we need to determine the length of fabric required to make one coat. Let's assume that the length of fabric required to make one coat is y meters.

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

1. For the first piece of fabric: x * y = 96 (Equation 1) 2. For the second piece of fabric: (x - 3) * y = 84 (Equation 2)

To solve this system of equations, we can use substitution or elimination method. Let's use the substitution method.

From Equation 1, we can express y in terms of x: y = 96 / x.

Substituting this value of y into Equation 2, we get:

(x - 3) * (96 / x) = 84

Simplifying the equation:

96 - 288 / x = 84

Multiplying both sides by x to eliminate the fraction:

96x - 288 = 84x

Bringing all the x terms to one side:

96x - 84x = 288

Simplifying:

12x = 288

Dividing both sides by 12:

x = 24

Now that we have the value of x, we can substitute it back into Equation 1 to find the value of y:

y = 96 / x = 96 / 24 = 4

Therefore, each coat requires 4 meters of fabric.

Answer

From the first piece of fabric measuring 96 meters, we can make 24 coats, and from the second piece of fabric measuring 84 meters, we can make 21 coats.
