Question

Julia shops at two different stores, Felipe’s Foods, and Desean’s Deli. She compares the prices in the two stores to determine which one has the better buy on the items she needs. Use the table to select the correct answers for Blank A, Blank B, and Blank C.

Answer 1

Answer:

A. Desean's; B.  Felipe's; C. Felipe's

Step-by-step explanation:

1. Cereal

(a) Felipe

$\text{Cost} = \frac{4.10}{9 \frac{3}{4} } = \frac{4.10}{\frac{39}{4}} = 4.10 \times \dfrac{4}{39} = \text{\ 0.42/oz}$

(b) Desean

$\text{Cost} = \frac{0.75}{5\frac{1}{8} } = \frac{0.75}{\frac{41}{8}} = 0.75 \times \dfrac{8}{41} = \text{\ 0.15/oz}$

Desean's is the better buy.

2. Applesauce

(a) Felipe

$\text{Cost} = \frac{3.05}{15 \frac{1}{3} } = \frac{3.05}{\frac{46}{3}} = 3.05 \times \dfrac{3}{46} = \text{\ 0.20/oz}$

(b) Desean

$\text{Cost} = \frac{6.76}{22\frac{2}{5} } = \frac{6.76}{\frac{112}{5}} = 6.76 \times \dfrac{5}{112} = \text{\ 0.30/oz}$

Felipe's is the better buy.

3. Soup

(a) Felipe

$\text{Cost} = \frac{1.85}{15 \frac{3}{5} } = \frac{1.85}{\frac{78}{5}} = 1.85 \times \dfrac{5}{78} = \text{\ 0.12/oz}$

(b) Desean

$\text{Cost} = \frac{3.85}{25\frac{3}{8} } = \frac{3.85}{\frac{203}{8}} = 3.85 \times \dfrac{8}{203} = \text{\ 0.15/oz}$

Felipe's is the better buy.
