Answer 1

Answer:

The answer is A.

Answer 2

Answer: Size D is the best buy.

Step-by-step explanation:

Since we have given that

Size A The 7 1/5 -ounce can costs $3.49.

Unit rate would be

$3.49\div 7\dfrac{1}{5}\\\\=3.49\div \dfrac{36}{5}\\\\=3.49\times \dfrac{5}{36}\\\\=\ 0.48$

Size B The 16 1/2 -ounce can costs $6.49.

Unit rate would be

$6.49\div 16\dfrac{1}{2}\\\\=6.49\div \dfrac{33}{2}\\\\=6.49\times \dfrac{2}{33}\\\\=\ 0.39$

Size C The 24 3/4 -ounce can costs $8.49.

Unit rate would be

$8.49\div 24\dfrac{3}{4}\\\\=8.49\div \dfrac{99}{4}\\\\=8.49\times \dfrac{4}{99}\\\\=\ 0.34$

Size D The 30 2/3 -ounce can costs $10.99

Unit rate would be

$10.99\div 30\dfrac{2}{3}\\\\=10.99\div \dfrac{92}{3}\\\\=10.99\times \dfrac{3}{92}\\\\=\ 0.33$

since all the unit rates are less than 1 dollar.

so, Size    Unit rate

    A                 0

    B                 0

    C                 0

    D                 0

Hence, Size D is the best buy.
