Let

x = the number of tapers (each coss \$1)

y = the number of pillars (each costs \$4)

z = the number of jars (each costs \$6)

There are 8 candles in each basket, therefore

x + y + z = 8 (1)

The cost per basket is \$24, therefore

x + 4y + 6z = 24 (2)

The number of tapers equals the sum of pillars and jars, therefore

x = y + z (3)

Substitute (3) into (1) and into (2).

y + z + y + z = 8

2y + 2z = 8

y + z = 4 (4)

y + z + 4y + 6z = 24

5y + 7z = 24 (5)

From (4), y = 4 - z. Substitute into (5).

5 (4 - z) + 7z = 24

2z + 20 = 24

2z = 4

z = 2

y = 4 - z = 4 - 2 = 2

x = y + z = 2 + 2 = 4

Answer: 4 tapers, 2 pillars, 2 jars.
