Question

Bradley is 160 years old. Adriana is 25 years old. How many years until Bradley's age is 4 times Adriana's age?

a) 40 years
b) 35 years
c) 30 years
d) 25 years

Answer 1

It will take 20 years until Bradley's age is 4 times Adriana's age.

Step-by-step explanation:

Let's assume x years from now, Bradley's age will be 4 times Adriana's age.

Bradley's age x years from now = 160 + x

Adriana's age x years from now = 25 + x

According to the problem, Bradley's age x years from now is 4 times Adriana's age x years from now:

160 + x = 4(25 + x)

Now, solve the equation to find x:

160 + x = 100 + 4x

3x = 60

x = 20

So, it will take 20 years until Bradley's age is 4 times Adriana's age.
