Question

Trina said that $1.05 + $2.25 = $3.35 because a dollar and 2 quarters plus 2 dollars and a quarter equals 3 dollars and 3 quarters. Do you agree or disagree with her statement? Explain.

Answer 1

No, I do not agree

Explanation:

Recall :

1 quarter = 25 cents = $0.25

Therefore,

$1 and 2 quarters ; $1 and 2(0.25) =50 cents = $1.50

2 dollars and a quarter ; $2 and 0.25 = $2.25

Adding both:

$1.50 + $2.25

__ $1. 50

__ $2.25

________

__$3.75

_______

The sum is $3.75 and not $3.25

$1 and 2 quarters ; $1 and 2(0.25) =50 cents = $1.50 and not $1.05
