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.
