shown below.

was $389.76, what was the cost,
in dollars, of the wallpaper per
square foot?
show your work.
14.5 feet
32 feet

Explanation:

Step1: Convert mixed number to fraction

$1\frac{2}{3} = \frac{5}{3}$ ounces

Step2: Find batches per ounce

$\text{Batches per ounce} = \frac{4.5}{\frac{5}{3}} = 4.5 \times \frac{3}{5} = 2.7$

Step3: Calculate total batches for 10 oz

$\text{Total batches} = 2.7 \times 10 = 27$

---

Step1: Calculate wall area

$\text{Area} = 14.5 \times 32 = 464$ square feet

Step2: Find cost per square foot

$\text{Cost per sq ft} = \frac{389.76}{464} = 0.84$

Answer:

1. 27 batches
2. $\$0.84$ per square foot
