Let's say make the shapes, some variable name
say
⛁ ⚪ ◽ ▯
a b c d
so.. if take those are the shapes provided
then we can take a look at the first set and we can say that
2a + b + c = 20
a + 4d + b = 19
a + c = 9
3c + d + a = 19
thus

and surely you can find the other two
To determine how many oil changes you will need the first year, you can calculate the number of miles driven the first year and then use that to determine how many groups of 3000 miles you will drive after the first 5000 miles.
1. 52 x 250 = 13000 miles
2. 13000 miles - 5000 miles (1 oil change) = 8000 miles
3. 8000 miles - 3000 miles (1 oil change) - 3000 miles (1 oil change) = 2000 miles
The first year, you will need 3 oil changes.
Answer:
By using the similarity method:
3960/50 = 4015/W
W = 50 x 4015/3960
W = 50.694
Rounds off to = 50.7
