Answer is B.
We see the center lines are 80 and 85 as stated.
A is wrong because the range of class 2 is less.
C is wrong; class 2 has a minimum of 50
D is wrong; class 2 has a smaller interquartile range, which is the width of the boxes.
Answer:
208⅓ ft²
Step-by-step explanation:
The dimensions of Rachel's living room are 80 times the measurements on the scale drawing.
Calculate the width:
w = 80 × 1⅞
Convert the mixed number to an improper fraction = 80 × 15/8
Cancel the 8s = 10 × 15
= 150 in
Convert inches to feet = 150/12
Convert the improper fraction to a mixed number = (144 + 6)/12
= 12⁶/₁₂
Reduce the fraction to lowest terms = 12½ ft
Calculate the length
l = 80 × 2½ = 80 × 5/2 = 40 × 5 = 200 in = 200/12 = (192 + 8)/12
l = 16⁸/₁₂ = 16⅔ ft
Calculate the area
A = lw
A = 16⅔ × 12½
Convert the mixed numbers to improper fractions
A = 50/3× 25/2
Cancel the 2s
= 25/3 × 25
Multiply numerators and denominators
= 625/3
Convert the improper fraction to a mixed number
= (624 + 1)/3
= 208⅓ ft²
The area of Rachel's living room is 208⅓ ft².
$50 corresponds to 4 kg
That means there must be a number that when you multiply by 4 you get 50.
Let that number be k. k is the price of cheese per kg.
1 kg: y = k * 1
2 kg: y = k * 2

To answer this question you need to interpret the ratio of the money correctly. We only know Dwayne money, so it's better to solve the ratio which was related to Dwayne. In this case, it was Kendra or Tom.
Dwayne money = $5
Kendra money= 1/10 Dwayne money= 1/10 x $5= $0.5
Juan money= 1/10 Kendra money = 1/10 x $0.5= $0.05
Tom money = 10 x Dwayne money = 10 x $5 = $50
Ruth money = 10 x Tom money = 10 x $50= $500
