Final answer:
To find the number of hits Sharon can expect this season, we compare the proportion of hits to the number of at bats.
Step-by-step explanation:
To find the number of hits Sharon can expect to get this season, we need to compare the proportion of hits in the previous season to the number of at bats in the current season.
Sharon got 45 hits out of 90 at bats last season, which can be expressed as a proportion: 45/90 = 0.5.
If Sharon is at bat 40 times this season, we can multiply this proportion by 40 to find the expected number of hits: 0.5 * 40 = 20.
Therefore, Sharon can expect to get 20 hits this season.
