Question

Jill buys 4 tickets to a concert. Each ticket costs $15.80. How much do all the tickets cost in total?

Answer 1

The total cost of all the tickets is $63.20.

Explanation:

There are two really quick ways to go about solving this problem, one involves addition, the other involves multiplication. Without further ado:

The problem says that each ticket costs $15.80, this means that if Jill has 1 ticket she paid $15.80. If Jill pays for 2 tickets then she's paid $15.80 twice, which means to find out how much Jill paid for the 2 tickets we can either use addition `($15.80+$15.80)` or we can multiply $15.80 by 2 `(2*$15.80)`. This is a good starting point, since we need to find out much she paid for 4 tickets adding `($15.80+$15.80)` or multiplying `(2*$15.80)` gives us half of the price of the 4 tickets. So, we can either use:

Addition

`($15.80+$15.80)= $31.60`

or:

Multiplication

`(2*$15.80)= $31.60`

Now we know that the price of 2 tickets is `$31.60`. So the price of 4 tickets can be found by either:

Addition

`($31.60+$31.60)= $63.20`

or:

Multiplication

`(2*$31.60)= $63.20`

This means that 4 tickets cost Jill `$63.20`.

-------------------------------------------------

I find it easier to break things into smaller chunks when doing math (it makes things easier), which is what I did above, however what I did above is the same as:

Addition

`($15.80+$15.80+$15.80+$15.80)= $63.20`

or:

Multiplication

`(4*$15.80)= $63.20`

I hope this helps!
