Question

Cody bought a hamburger for $3 and

a milkshake for $2. He paid for his
meal with a twenty dollar bill. Which
expression shows how much change he
should receive?
20+(3+2)
20 - (3-2)
(20 - 3) + 2
20 - (3 + 2)​

Answer 1

Add $3(hamburger and $2(milkshake) You'll get $5.

The last expression has 3+2 in parenthesis(). It's 5 as well.

Then subtract $5 from 20.

It's not the first expression because you're adding 20 and 5.You had to subtract.(20-5)

Answer:20 - (3+2)

Answer 2

The answer would be 20-(3+2) because first you do what is inside the parentheses 3+2=5 and now you have to subtract 20-5=15. Cody’s change should be $15.
