AAA Taxi charges $1.75 for the first mile and $1.05 for each additional mile. How far could Mrs. Leslie travel for $20 if she ti
MArishka [77]

Answer:

She can travel 15 miles

Step-by-step explanation:

I first found my answer by adding 1.75 and 2.50 together

giving me 4.25

I then made the equation

4.25+ 1.05x = 20

Subtract 4.25 from both sides that leaves you with

1.05x = 15.75

divide 1.05x on both sides

x= 15 is your solution

Mr moore has saved the liscense plates from all his cars. He has nailed them to a wall in his garage. The wall is 5 meters long
QveST [7]

Answer: 270

Step-by-step explanation:

I might be wrong on this one, but the average license plate is 12 in by 6 in. One meter is around 3 feet. The dimensions of the wall are 9 feet by 15 feet.

Length wise, 15 license plates can fit on the wall, and bright wise, 18 can fit on the wall.

15 times 18 = 270

270 license plates is your answer
