60% of a museum’s fossils are from the Jurassic Period. If the number of fossils from the Jurassic period is 15, what is the total number of fossils at the museum?
A
9
B
910
C
25
D
40
Let's calculate the total number of fossils in the museum. We know that 60% of the fossils are from the Jurassic Period, and we are given that this percentage represents 15 fossils.
Let's assume the total number of fossils in the museum is x. We can set up the following equation based on the information given:
0.60x = 15
To solve for x, we divide both sides of the equation by 0.60:
x = 15 / 0.60
x = 25
Therefore, the total number of fossils at the museum is 25.
The correct answer is C.
