Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

Reba has a home-based business making corsages and boutonnieres for school dances. Last year, she sold 35 corsages and 29 boutonnieres, which brought in a total of $1,408. This year, she sold 24 corsages and 15 boutonnieres, for a total of $858. How much does each item sell for?

A corsage sells for $
, and a boutonniere sells for

Respuesta :

The amount a corsage and a boutonniere sells for this year is taken as

the same as the amount they where sold last year.

The system of equations is presented as follows;

  • 35·x + 29·y = 1,408
  • 24·x + 15·y = 858

  • A corsage sells for $22, and a boutonniere sells for $22

Methods uses to write a system of equations

Last year, she sold 35 corsages and 29 boutonnieres = $1,408

This year, she sold 24 corsages and 15 boutonnieres = $858

Required:

How much does each item sell for

Solution:

Let x represent the price of each corsages, and let y represent the price

of each boutonnieres sold, we have, the following system of equations;

  • 35·x + 29·y = 1,408...(1)
  • 24·x + 15·y = 858...(2)

Making y the subject of equation (1), gives;

  • [tex]y = \mathbf{\dfrac{1,408}{29} - \dfrac{35}{29} \cdot x}[/tex]

Therefore;

[tex]24 \cdot x + 15 \times \left(\dfrac{1,408}{29} - \dfrac{35}{29} \cdot x \right) = \mathbf{\dfrac{171\cdot x + 21120}{29}} = 858[/tex]

171·x + 21120 = 858 × 29 = 24,882

171·x = 24,882 - 21,120 = 3,762

  • [tex]x = \dfrac{3,762}{171} = \mathbf{22}[/tex]

Therefore;

  • Each corsage sells for, x = $22

[tex]y = \mathbf{\dfrac{1,408}{29} - \dfrac{35}{29} \times 22} = 22[/tex]

  • Each boutonniere sells for, y = $22
