Answer: The correct answer is Choice C.
Step-by-step explanation: The cost of the ride is .50 per mile, plus $3.00 for each ride. In order to calculate it, the correct formula is going to multiply the number of miles, represented by x, by .50, and then add $3 for the ride.
Choice C is doing just that. $.50x + $3
Answer: You are right.
Step-by-step explanation: The amount of gas you have will only get you 115.2 Miles and the gas station is 116 miles away.
19.2 % 3 = 6.4
6.4 x 18 = 115.2
SCale factor is ML/DC = 6/4 = 3/2
So multiply AD by 3/2 to find the length of JM . The length would be 3*3/2=9/2
Next find the perimeter of JKML. It would be 2(9/2+6)=21
