Aiden bought 2 iPads for a total of $480. At this rate, what is the cost of 3 iPads?

Sagot :

Answer:

The cost of three would be $720.

Step-by-step explanation:

First you need to divide 480 by 2 which gives you 240. 240 is the cost of one iPad so 240 times 3 is 720.

Answer:

$720.

Step-by-step explanation:

Karleebordelon6 has a wonderful answer, but I will provide a slightly different approach.

This can be solved by using proportions.

Take a look:

[tex]\frac{2 (ipads)}{480 (dollars)} =\frac{3 (ipads)}{x}[/tex]

After setting up the proportion, we can cross multiply.

[tex]480 * 3 = 1440\\[/tex]

[tex]2 *x = 2x[/tex]

Lastly, divide both products.

[tex]2x = 1440[/tex]

[tex]1440/2 = 720[/tex]

Therefore, the total cost of 3 iPads is $720.

In other words, x = 720.

[tex]\frac{2(ipads)}{480(dollars)} =\frac{3( ipads)}{720(dollars)}[/tex]
