Answer:
(amounts could be:)
Katia: $3.50
Mateo: $1.75
Step-by-step explanation:
<em>Remember that a quarter = $0.25, 4 quarters = $1.00</em>
<h3>We know that they both have 38 quarters ($9.50) </h3>
<em>after an hour of playing games in the arcade, Katia has $1.75 more than Mateo</em>
lets say that Katia has <em>(random amount)</em><em>$3.50(14 quarters) </em>and Mateo has $1.75 less than that.
$3.50 - $1.75 = $1.75
<h3>Katia has $3.50 and Mateo has $1.75.</h3>
