An online store sells two types of speaker docks for smartphones. the higher-priced speaker dock sells for $190 and the lower-priced speaker dock sells for $80. last week the store sold three times as many lower-priced speaker docks as higher-priced speaker docks. combined sales totaled $3,440. how many of each did it sell?

8 higher-priced speaker and 24 lower-priced speaker docks are sold.

Step-by-step explanation:

Let x be the no. of  higher-priced speaker sold

We are given that the store sold three times as many lower-priced speaker docks as higher-priced speaker docks.

So,  the no. of lower-priced speaker sold = 3x

Cost of 1 higher-priced speaker dock = $190

Cost of x higher-priced speaker dock = $190x

Cost of 1 lower-priced speaker dock = $80

Cost of 3x lower-priced speaker dock = $80(3x)=$240x

So, total cost = 190x+240x=430x

We are given that Combined sales totaled $3,440.

So,

So,The no. of higher-priced speaker sold is 8

The no. of lower-priced speaker sold = 3x = 3(8) =24

Hence 8 higher-priced speaker and 24 lower-priced speaker docks are sold.
