Answer:
3,471 regular keyboards sold
1,157 wireless keyboards sold
Step-by-step explanation:
To represent this scenario use this system of equations:
x + y = 4628
x = 3y
x = regular keyboards
y = wireless keyboards
The first equation represents how many regular and wireless keyboards were sold to equal 4,628 units of keyboards.
The second equation represents how there are three times as many regular keyboards sold than wireless.
Solve this by plugging in x in the second equation to the first equation:
(3y) + y = 4628
4y = 4628 Add the y's together to get 4y
y = 1,157
Therefore, 1,157 wireless keyboards were sold
To find how many regular keyboards were sold, plug y back into the second equation:
x = 3(1157)
x = 3,471
The final answer to this problem is that 3,471 regular keyboards were sold and 1,157 wireless keyboards were sold.
