Question

The double number line shows the price of
1 cupcake. Complete the table to show the same information as the double number line.

Answer 1

Answer:

According to the first image, 1 cupcake costs $1.5.

So, we can use the rule of three to complete the table.

If 1 cupcake costs $1.5, 5 cupcakes would be $1.5(5)=$7.50

And 18 cupcakes would be $1.5(18)=$27.

However, $18 how many cupcakes represent?

$\frac{18}{1.5}=12$

Therefore, 12 cupcakes costs $18.

So, the table would be:

Cupcakes     Prices

      5             $7.50

     12             $18

     18             $27
