Answer:

12 hits

Step-by-step explanation:

Let x be the number of hits needed

1 hit equals an at-bat.

(45+x)hits / (130+x)at-bats = 0.4

(45+x) = 0.4(130+x)

45 + x = 52 + 0.4x

45 - 52 = 0.4x - x

-7 = -0.6x

x = -7/-0.6

x = 11.667

x = 12(approximately)

12 hits are necessary since there are no fraction of hits
