Question

rashen bought 15 fish sticks for $31.50. how much would it cost for 14 fish sticks?

Explanation:

Step1: Find the cost of one fish - stick

We divide the total cost by the number of fish - sticks. Let the cost of one fish - stick be $x$. Then $x=\frac{31.50}{15}$.
$x = 2.1$

Step2: Find the cost of 14 fish - sticks

We multiply the cost of one fish - stick by 14. Let the cost of 14 fish - sticks be $y$. Then $y=14\times x$.
$y = 14\times2.1=29.4$

Answer:

$29.4$
