Hello There!

A is not true because overall 22% had trucks of the 100 people while only 9% overall had a van. So more people overall had trucks then vans meaning that vans has the lowest percentage of type of vehicle driven therefore we can eliminate answer choice A

B is also incorrect because from ages 41-50, a total of 14 people drive a van or sedan. Also from ages 41-50, a total of 14 people drive a SUV or truck. Because the total of people that drive each of the grouped vehicles is the same neither of the percentages would be lower or higher therefore we eliminate answer choice B

C is also incorrect because the same amount of people in the age group 31-40 drive trucks as the amount of people in the age group 41-50. Because the same amount of people from the different age groups drive trucks the percentage would be neither higher nor lower therefore C is incorrect

D is the correct answer choice because the total amount of people that drive trucks from the age range 21-30 is the same as the amount of people that drive a truck from other age groups. Or to be more specific the sum of the people who drive a truck from ages 31-40, 41-50 and over 50 is 11 (3+4+4=11) This meaning that the same percentage of people in the age range from 21-30 that drive a truck is the same as the percentage of people that drive a truck from the sum of the other age ranges. Hence the correct answer choice is D

Answer is D

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?

Answers

Answer:

1 hour 42 minutes approx

Step-by-step explanation:

Given data

Mayas work rate= 1/4 room per hour

Reginald work rate= 1/3 room per hour

Let the total time taken for both of them be T

Hence their combined work rate

1/4+1/3= 1/T

3+4/12=1/T

7/12=1/T

T= 12/7

T= 1.7 hours

Hence it will take them 1 hour 42 minutes approx

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?

Answers

Answer:

Cereal A is cheaper by $0.15

Step-by-step explanation:

Cost of a 10-ounce box of Cereal A = $2.70

So,

Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]

Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]

Also,

Cost of a 13-ounce box of Cereal B = $3.64

So,

Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]

Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]

Here,

Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]

Therefore,

Cereal A is cheaper by $0.15
