Question

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

Answer 1

$720.

Explanation:

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

This can be solved by using proportions.

Take a look:

`(2 (ipads))/(480 (dollars)) =(3 (ipads))/(x)`

After setting up the proportion, we can cross multiply.

`480 * 3 = 1440\\`

`2 *x = 2x`

Lastly, divide both products.

`2x = 1440`

`1440/2 = 720`

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

In other words, x = 720.

`(2(ipads))/(480(dollars)) =(3( ipads))/(720(dollars))`

Answer 2

The cost of three would be $720.

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.
