Answer:
1. The correct answer is option B.
2. The correct answer is option A.
3. The correct answer is option B.
4. The correct answer is option C.
Step-by-step explanation:
1.
Store A sells 11 bagels for $9.57.
Price of 1 bagel = [tex]\frac{\$9.57}{11}=\$0.87[/tex]
Store B sells 4 bagels for $3.52.
Price of 1 bagel at store B= [tex]\frac{\$3.52}{4}=\$0.88[/tex]
Price of bagel at store B > Price of bagel at store A
$0.88 > $0.87
Difference in the price of bagel = $0.88 - $0.87= $0.01
The correct answer is option B.
2.
i) $10.88 for 7 cans of tuna
Price of single can = [tex]\frac{\$10.88}{7}=\$1.55[/tex]
ii) $11.55 for 6 cans of tuna
Price of single can = [tex]\frac{\$11.55}{6}=\$1.92[/tex]
iii) $17.25 9 cans of tuna
Price of single can = [tex]\frac{\$17.25}{9}=\$1.91[/tex]
iv) $15.31 8 cans of tuna
Price of single can = [tex]\frac{\$15.31}{8}=\$1.91[/tex]
The best buy is ,$10.88 for 7 cans of tuna because 1 can of tune cost only$1.55.
3.
Population in the state = 626,011
Area occupied by the population = 9,620 square miles
Population density of the state:
[tex]\frac{626,011}{9,620 mile^2}=65.07 people/mile^2\approx 65 people/mile^2[/tex]
4.
A. 20/25, 14/21
[tex]\frac{20}{25}=\frac{14}{21}[/tex]
[tex]\frac{4}{5}\neq \frac{2}{3}[/tex] (not a proportion)
B. 10/23, 18/7
[tex]\frac{10}{23}=\frac{18}{7}[/tex]
[tex]\frac{10}{23}\neq \frac{18}{7}[/tex] (not a proportion)
C. 5/45, 4/36
[tex]\frac{5}{45}=\frac{4}{36}[/tex]
[tex]\frac{1}{9}=\frac{1}{9}[/tex] ( proportion)
D. 5/4, 4/5
[tex]\frac{5}{4}=\frac{4}{5}[/tex]
[tex]\frac{5}{4}\neq \frac{4}{5}[/tex] (not a proportion)
