Ralph is 3 years old

Casey is 18 years old

Step-by-step explanation:

Let the age of Ralph be x

Then Casey is 6 times as old as Ralph will be 6x

In two years

Ralph =x+2

Casey=6x+2 ⇒ 4(x+2)

Equate the two equations for Casey as

6x+2 = 4x+8

6x-4x=8-2

2x=6

x=6/2= 3

Current age;

Ralph= x= 3 years old

Casey=6x = 6*3= 18 years

Liula [17]

Answer: It costs $1.22 to make each paperweight.

Step-by-step explanation:

Given : Selling price of 95 identical paperweights = $230.85

Then, Selling price of 1 paperweight = (Selling price of 95 identical paperweights) ÷ 95

= $ (230.85 ÷ 95) = $ 2.43

Now, selling price of each paperweight = 2 x ( cost of each paperweight)

⇒ cost of each paperweight = (selling price of each paperweight ) ÷ 2

⇒ cost of each paperweight = $ 2.43 ÷ 2 = $ 1.215 ≈ $ 1.22

Hence, it costs $1.22 to make each paperweight.
