Question

if naomi's age is 5 less than 3 times kat'ys age and Naomi is 28 how old is katy

Answer 1

Let's denote Katy's age as \( k \).

According to the information given:

Naomi's age is 5 less than 3 times Katy's age. This can be expressed with the equation:

\[
N = 3k - 5
\]

We know that Naomi's age (\( N \)) is 28. Therefore, we can substitute 28 into the equation:

\[
28 = 3k - 5
\]

Now, let's solve for \( k \):

1. Add 5 to both sides:

\[
28 + 5 = 3k
\]
\[
33 = 3k
\]

2. Divide by 3:

\[
k = \frac{33}{3} = 11
\]

So, Katy is 11 years old.
