Question

if 3 pencils cost $1.50, how much would 10 pencils cost at the same rate?

Explanation:

Step1: Find cost per pencil

To find the cost of one pencil, divide total cost by number of pencils.
$\frac{1.50}{3} = 0.50$ dollars per pencil.

Step2: Calculate cost for 10 pencils

Multiply cost per pencil by 10.
$0.50 \times 10 = 5.00$

Answer:

$5.00$
