I took the test.
Answer:
No, the answer is not reasonable. It should be about 10 pounds.
Step-by-step explanation:
Given,
The quantity of hot dog bought by Jill's club = [tex]4\frac{2}{5}[/tex] pounds,
Hot dog = [tex]3\frac{1}{2}[/tex] pounds
Hamburger = [tex]2\frac{3}{10}[/tex] pounds
So, the total quantity of meat they bought
[tex]=4\frac{2}{5}+3\frac{1}{2}+2\frac{3}{10}[/tex]
[tex]=\frac{22}{5}+\frac{7}{2}+\frac{23}{10}[/tex]
[tex]=\frac{44+35+23}{10}[/tex] ( Adding fractions ),
[tex]=\frac{102}{10}[/tex]
[tex]=10.2\text{ pounds}[/tex]
Since, [tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex]
[tex]\implies 8.5\neq 10.2[/tex]
Hence, the student's answer is not reasonable it should be about 10 pounds.
Third option is correct.
