Question 23.
The Ruiz family, 2 adults and 2 children, visit the science museum. The Brinker family, 1 adult and 3 children, visit the zoo. Each family has $60.00 to spend on admission. Which family will spend less on admission?
Answer:
The Brinker family will spend less on admission.
Explanation:
Cost of adult admission for visit the science museum = $15.00
Cost of children admission for visit the science museum = $10.00
Number of adults in Ruiz family for visit the science museum = 2.
Number of children in Ruiz family for visit the science museum = 2.
Total cost for admission for visit the science museum of Ruiz family = (Cost of adult admission for visit the science museum × Cost of adult admission for visit the science museum) + (Number of children in Ruiz family for visit the science museum × Cost of children admission for visit the science museum)
= (2 × $15) + (2 × $10)
= $30 + $20
= $50.
Cost of adult admission for visit the zoo = $13.50.
Cost of children admission for visit the zoo = $9.50.
Number of adults in Brinker family for visit the zoo = 1.
Number of children in Brinker family for visit the zoo = 3.
Total cost for admission for visit the zoo of Brinker family = (Cost of adult admission for visit the zoo × Number of adults in Brinker family for visit the zoo) + (Cost of children admission for visit the zoo × Number of children in Brinker family for visit the zoo)
= (1 × $13.50) + (2 × $9.50)
= $13.50 + $19.00
= $32.50.
Each family has $60.00 to spend on admission.
Comparison:
Total cost for admission for visit the science museum of Ruiz family = $50.
Total cost for admission for visit the zoo of Brinker family = $32.50.
Difference:
$60 – $50 = $10.
$60 – $32.50 = $27.50.
Question 24.
A bird-watcher measured the heart rate of a blue-throated hummingbird at 1,260 beats per minute. She read that an inactive hummingbird may have a heart rate as low as 50 beats per minute. What is the difference between these heart rates?
Answer:
1,210 is the difference between these heart rates.
Explanation:
Heart rate of a blue-throated hummingbird = 1,260 beats per minute.
Heart rate of an inactive hummingbird = 50 beats per minute.
Difference:
Heart rate of a blue-throated hummingbird – Heart rate of an inactive hummingbird
= 1,260 – 50
= 1,210.
