Answer: 3/40
Step-by-step explanation:
What we know:
- 1/5 of the baseball cards are California players
- 38 of this 1/5 are from SDP players
How to solve:
We need to find the fraction of cards that have SDP players from the total collection. This can be done by converting it into a decimal and then matching it with one of the options.
Process:
Decimal of California Cards
Set up equation x = 1/5
Solve x = 0.2
Decimal of SDP Cards
Set up equation y = (x/100)*38
Substitute y = (0.2/100)*38
Simplify y = 0.002*38
Solve y = 0.076
Matching
A
Set up equation a = y
Substitute 23/40 = 0.076
Simplify 0.575 = 0.076
B
Set up equation a = y
Substitute 4/13 = 0.076
Simplify 0.308 = 0.076
C
Set up equation a = y
Substitute 3/40 = 0.076
Simplify 0.075 = 0.076
Answer: 3/40
