At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard. Here is a system of equations that represent the constraints in the situation. x + y = 4.25 16.90x + 4y = 36.35 Find the solutions to the system of equations. Explain or show your reasoning

Given:

The system of equations that represent the constraints for the given situation is

To find:

The solution of given system of equations.

Solution:

We have,

          ...(i)

          ...(ii)

Multiply equation (i) by 4.

          ...(iii)

Subtracting (iii) from (ii), we get

Divide both sides by 12.90.

Put this value in (i).

The solution of system of equations is x=1.5 and y=2.75. It means, the yards of silk are 1.5 and yards of cotton are 2.75.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
