Final answer:
Sara receives $16 and Zara receives $24 when sharing a $40 reward in a 2:3 ratio.
Step-by-step explanation:
Sara and Zara share a reward of $40 in a ratio of 2:3. To determine how much each gets, we must first add the parts of the ratio together, which is 2+3=5 parts in total. Since the reward is $40, we divide this amount by the total number of parts, which gives us $8 per part. Now, we multiply $8 by the number of parts each person gets, which is 2 parts for Sara and 3 parts for Zara.
$8 per part x 2 parts for Sara = $16 for Sara
$8 per part x 3 parts for Zara = $24 for Zara
Sara receives $16 and Zara receives $24 from the $40 reward.
