Answer: A. $0.60

Step-by-step explanation:

The prices for which the carpets were sold are

1) 100 square feet for $67

2) 200 square feet for $130

3) 400 square feet for $240

4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes

1) 1 square feet costs 67/100 = $0.67

2) 1 square feet costs 130/200 = $0.65

3) 1 square feet costs 240/400 = $0.6

4) 1 square feet costs 504/800 = $0.63

The unit cost per square foot of carpet for the worst deal is $0.6

Which expression has the greatest value |-21|, |14|, |30|, |-45|
tresset_1 [31]

Answer:

|-45|

Step-by-step explanation:

In mathematics, the absolute value of a real number is the numeric value of the  number, regardless the sign, either this is positive or negative.

The absolute value function can be definied as:

  • |a|=a si a ≥0
  • |a|=-a si a <0

Using this definition, we have:

|-21| = -(-21) = 21

|14| = 14

|30| = 30

|-45| = -(-45) = 45

Therefore, the expression |-45| has the greatest value.
