4 similar pencils cost $1.90. Find the cost of 24 such pencils.

Answer 1

We can set up a proportion to find the cost of 24 pencils.

Let x represent the cost of 24 pencils.

We know that 4 pencils cost $1.90.

So, we have the proportion:

4 pencils / $1.90 = 24 pencils / x

Cross-multiplying, we get:

4x = $1.90 * 24

4x = $45.60

Dividing both sides by 4, we find:

x = $45.60 / 4

x = $11.40

Therefore, the cost of 24 pencils is $11.40.
