A mixture of 30 pounds of candy sells for $1.10 a pound. The mixture consists of chocolates worth $1.50 a pound and chocolates worth 90¢ a pound. How many pounds of the $1.50 chocolate were used to make the mixture? If x represents the pounds of $1.50 chocolates used, then which of the following represents the pounds of 90¢ chocolates used?

x
30 - x
30

10 pounds of the $1.50 chocolate were used.

30 - x represents the number of pounds of the 0.90 chocolate used.

Step-by-step explanation:

30 * 1.10 = 1.5x + 0.9 (30 - x)

33 = 1.5x + 27 - 0.9x

0.6x = 6

x = 10
