PC Solutions sells regular keyboards for $75 and wireless keyboards for $106. Last week the store sold four times as many regular keyboards as wireless. If total keyboard sales were $6,496, how many of each type were sold?

Respuesta :

Answer: There are 16 wireless and 64 regular keyboards.

Step-by-step explanation:

Since we have given that

Cost of regular keyboards = $75

Cost of wireless keyboards = $106

Let the number of wireless keyboards be 'x'.

Let the number of regular keyboards be '4x'.

Total cost = $6,496

According to question, we get that

[tex]75\times 4x+106\times x=6496\\\\300x+106x=6496\\\\406x=6496\\\\x=16[/tex]

So, there are x = 16 wireless keyboards and 16×4 = 64 regular keyboards.

Hence, there are 16 wireless and 64 regular keyboards.
