Answer:
Josie should purchase floral daisy wallpaper.
Step-by-step explanation:
Area = Length × Width
The area of the Josie's accent wall = 9 × 10 = 90 feet²
The cost of Floral Daisy per square feet
=
=
= 0.98534 ≈ $0.99/ft²
The cost of total wallpaper for the wall = 90 × 0.99 = $89.10
The cost of Flower Power per square feet =
=
= 1.0096 ≈ $1.01/ft²
The cost of total wallpaper for the wall = 90 × 1.01 = $90.90
total savings = 90.90 - 89.10 = $1.80
∵ The floral daisy wallpaper comes in size = 1.45 ft × 9.8 ft
∴ Josie needs the number of rolls of floral daisy wallpaper to cover her wall = 7
The cost of 7 rolls = 14.67 × 7 = $102.69
To cover her wall with flower power wallpaper, she needs the number of rolls = 2
The cost of 2 rolls = 99 × 2 = $198
We can see the cost of floral daisy wallpaper is less than flower power.
Therefore, Josie should purchase floral daisy wallpaper.
This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator.

. This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that
is greater than
because it is greater than its equivalent fraction.
