The company can produce 20 desktop keyboards and 10 laptop keyboards
Step-by-step explanation:
A company manufactures keyboards for desktop and laptop computers
We need to find how much of each type the company can produce
Assume that the company can produce x desktop keyboards and
y laptop keyboards
∵ The company can produce x desktop keyboards
∵ company can produce y laptop keyboards
∵ The desktop keyboard contains 105 keys
∵ The laptop keyboard has 90 keys
∵ The company has 3000 keys
- Write an equation to represent the total keys
∴ 105 x + 90 y = 3000 ⇒ (1)
∵ The company needs to produce twice as many desktop keyboards
as laptop keyboards
∴ x = 2 y ⇒ (2)
Substitute x in equation (1) by equation (2)
∵ 105(2 y) + 90 y = 3000
∴ 210 y + 90 y = 3000
∴ 300 y = 3000
- Divide both sides by 300
∴ y = 10
∴ The company can produce 10 laptop keyboards
Substitute the value of y in equation (2) to find the value of x
∵ x = 2(10)
∴ x = 20
∴ The company can produce 20 desktop keyboards
The company can produce 20 desktop keyboards and 10 laptop keyboards
