Answer 2

Answer with explanation:

Ques 1)

A van travels 240 miles on 20 gallons of gas.

This means that 20 gallons of gas is used to travel 240 miles.

This means that:

1 gallon of gas is used to travel  :

              $\dfrac{240}{20}=12\ miles$

Hence, it travels 12 miles per gallon.

Ques 2)

Carlos installed 24 wooden cabinets in 8 days.

i.e. in 8 days he install 24 cabinets

This means in 1 day he will install

$\dfrac{24}{8}=3\ cabinets$

On the average, he will  install 3 cabinets each day.

Ques 3)

100 sheets cost $ 2.50

This means that cost of 1 sheet is: $ 0.0250

( since,   $\dfrac{2.50}{100}=0.0250$ )

150 sheets at $3.50

This means that cost of 1 sheet is: $ 0.0233

( since,  $\dfrac{3.50}{150}=0.02333$ )

This means that the cost per sheet is cheaper in the buy:

    150 sheets at $3.50.

Ques 4)

Pack A has 36 cookies for $5.90.

This means that cost of 1 cookie is: $ 0.16388 )

(  since,  $\dfrac{5.90}{36}=0.16388$ )

and  Pack B has 24 cookies for $4.10.

This means that cost of 1 cookie is: $ 0.170833

( since, $\dfrac{4.10}{24}=0.170833$ )

The cost per cookie is cheaper in Pack A.

Hence, the pack which has cheaper cookies is: Pack A.

Ques 5)

One is in retail and pays $500 for a 40-hour work week.

This means that the payment for 1 hour is: $ 12.5

( since, $\dfrac{500}{40}=12.5$ )

The other job is at a restaurant and pays $12 an hour.

This means that the job which has a higher hourly rate is:

In retail which pays $500 for a 40-hour work week.      

( since 12.5>12  )
