Answer 1

Answer:

Step-by-step explanation:

1 burger + 1 fries x 1 drink = 25

—————

3 drinks = 30 therefore dividing both sides by 3:

1 drink = 10

—————

1 cup + 2 burgers = 20 so:

10 + 2 burgers = 20 so:

10 + 2 burgers = 10 + 10 :

2 burgers = 10 therefore dividing both sides by 2:

1 burger = 5

1 burger + 2 fries* = 9 so:

5 + 2 fries = 9 so:

5 + 2 fries = 5 + 4 so:

2 fries = 4 therefore dividing both sides by 2:

1 fries = 2

(*fries is used to mean ‘one order of fries’

Gathering all of the bits we need we get the following solution:

1 burger + 1 fries x 1 drink = 5 + 2 x 10

Using order of operations   or BOMDAS

Without brackets or exponents the solution to the equation begins with multiplication.

5 + 2 x 10 = 5 + 20 then addition

5 + 20 = 25

∴1 burger + 1 fries x 1 drink = 25.
