## Solve McDonalds Math Puzzle:

Find the value of McDonalds Math Puzzle.

First of all we need to solve for every food & find its value. Then we can use this value in the final equation to solve the expression.

Drink + Drink + Drink = 30
3 Drink = 30
Drink = 10

Now we are going to solve the second expression.
Drink + Burger + Burger = 20
Drink + 2 Burger = 20
2 Burger = 20 – Drink

Using value of Drink in this equation, we get

2 Burger = 20 – 10
2 Burger = 10
Burger = 5

Now solving for the third equation. In this equation we need to find the value of chips which is the only unknown variable.

Burger + 2 Chips + 2 Chips = 9

Burger + 4 Chips = 9

4 Chips = 9 – Burger
Using value of Burger from previous equation, we get:

4 Chips = 9 – 5
4 Chips = 4
Chips = 1

Now finally we are going to solve the final expression:

Burger + Chips x Drink = ?

Using value of Burger, Chips & Drink, we get:

= 5 + 1 x 10

Using MDAS, we can solve this expression. MDAS stands for multiplication, division, addition & subtraction. It defines the order in which we can solve math operators. In above equation, we have addition & multiplication operators. So we need to solve for multiplication first because it has a higher priority.

= 5 + 1 x 10

= 5 + 10

= 15

The value of the McDonalds math puzzle is 15.
