Explanation:

Question 5

Step1: Find the cost per goldfish

From the table, when the number of fish is 1, the cost is $2.80. So the cost per goldfish is $2.80.

Step2: Calculate the cost for 6 goldfish

To find the cost for 6 goldfish, we multiply the cost per goldfish by 6. So the cost is $2.80\times6$.
$2.80\times6 = 16.80$

The statement $4m\cdot0\cdot3m = 0$ shows the Multiplicative Property of Zero, which states that any number multiplied by zero is zero.

The statement $5+(a + 17)=(5 + a)+17$ shows the Associative Property of Addition, which states that the way in which numbers are grouped when adding does not change the sum.

Answer:

$16.80$
