grin007 [14]

Answer:

Courtney and her family traveled 14 miles in Mr. De Palma's cab from the airport to the hotel.  

Step-by-step explanation:

The total amount of the ride, including tip, was $42.00.  Since this amount represents exactly eight times the amount that was received as a tip, 42/8 is $5.25, which is the cost of the tip.  The other flat rates associated with the trip is the $3.15 for entry and $1.75 for each additional passenger (1.75 x 3=5.25).  Once you subtract these fees from the total amount, $42 - $5.25 (tip) - $5.25 (additional passengers) - $3.15 (entry) = $28.35.  Since Mr. De Palma charges $0.45 for every two-ninths of a mile, you take the revised total 28.35/.45 = 63.  Since 63 represents the amount for every two-ninths of a mile, you need to multiply this amount by 2/9 to get your total amount of miles, or 63 x 2/9 = 14.

kiruha [24]

Answer:

48 different houses can be designed from these plans.

Step-by-step explanation:

O1 - O2 - O3 - O4

O1 is the number of different living rooms. So O1 = 3.

O2 is the number of different bedroom configurations. So O2 = 4.

O3 is the number of different garage styles. So O3 = 2.

O4 is the number of different outside configurations. So O4 = 2.

In all,

T = 3*4*2*2 = 48

48 different houses can be designed from these plans.
