Acompany sells trinkets and doodads. it costs the company $30 to make 4 trinkets and 2 doodads and $40 to make 3 trinkets and 4 doodads. how much does it cost to make trinkets and doodads?

The cost of one trinket is $4 and the cost of one doodads is $7.

Step-by-step explanation:

Let x represents the cost of one trinket and y represents the cost of one doodads,

Since, $ 30 to make 4 trinkets and 2 doodads,

⇒ 4x + 2y = 30 (1),

Also, $ 40 to make 3 trinkets and 4 doodads,

⇒ 3x + 4y = 40 (2),

Equation (2) - 2 × Equation (1),

We get,

-5x = - 20

⇒ x = 4

From equation (1),

16 + 2y = 30

⇒ 2y = 14

⇒ y = 7

Hence, the cost of one trinket is $ 4 and the cost of one doodads is $ 7.

i would say c is the best answer, hope it's right!

good luck! =)

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
