Each car in a rental fleet is either red or white, and there are 75 cars total. There are three more white than twice the number of red cars. How many cars are white?A) 24
B) 47
C) 48
D) 51

Answers

Answer 1

Answer: Answer is D) 51
Let red cars be x and white cars will be 2x+3
you have to find that number by which we can get the sum of all cars, 75
now there is only number which satisfied with the x=24
so white cats are 2(24)+3=51
and total cars are white+ red
51+24 = 75

Hello,

If W=7 then 2*W-3=14-3=11
Area=7*11=77
