Let the no. of station wagons be 'x' and no.of motorcycles be 'y'.
no. of tires on station wagon excluding spare tire is 4 and no. of tires on motorcycle excluding spare tire is 2.
Total number of tires at the dealer's depot is 4x+2y.
Given No. of Tires on the vehicles is 30 more than twice the number of vehicles,i.e., 30+2(x+y)=4x+2y
solving we get x=15

4w + 2c = 2 (w + c ) + 30

Or, 4w + 2c = 2w + 2c + 30

Or, 2w = 30

So, w = 15

Hence, the number of station wagons the dealer owns is (B) 15

To start we can define some variables:

w = the number of station wagons

m = the number of motorcycles

Since there are 4 tires on a station wagon and 2 tires on a motorcycle, the number of tires per station wagon is 4w and the number of tires per motorcycle is 2m.

We are given that the number of tires (excluding spare tires) on the vehicles is 30 more than twice the number of vehicles so we can create the following equation:

4w + 2m = 30 + 2(w + m)

4w + 2m = 30 + 2w + 2m

2w = 30

w = 15

Thus, there are 15 station wagons at the dealership.

Hi All,

Although the prompt does not state it, you are expected to know that each station wagon has 4 tires and each motorcycle has 2 tires. You might find it easiest to treat this algebraically:

W = number of station wagons
M = number of motorcycles

Total vehicles = W + M
Total tires = 4W + 2M

The number of tires is 30 more than twice the number of vehicles...

4W + 2M = 30 + 2(W+M)

Now we can combine like terms and simplify:

4W + 2M = 30 + 2W + 2M
2W = 30
W = 15

Final Answer:

B
