Question

Jose's batting average is 0.250 after 160 times at bat, which means he made a hit 40 of the times he was at

Answer 1

Answer:

The correct option is;

$\dfrac{x + 40}{x + 160} = 0.333$

Which is of the form of option C with 2 replaced by x and the characters formatted

Step-by-step explanation:

The given parameters are;

Jose's present batting average = 0.250

The number of times he was at bat = 160

The number of times he made a hit = 40

The batting average he wants to improve to = 0.333

If he makes a hit the next x times he was at bat is represented as if he makes a hit each time, for the next x time he was at bat. We have;

The number in times he makes a hit the next x times he was at bat = x

Therefore, we get;

New total number of hits Jose makes = 40 + x = x + 40

New total number of time Jose was at bat = 160 + x = x + 160

Therefore, given that Jose intends to improve his batting average to 0.333, and that the batting average is given by the relation;

$Batting \ average = \dfrac{The \ number \ of\ hits}{The \ number \ of\ at \ bat }$

To find x, we have;

$0.333 = \dfrac{x + 40}{x + 160}$

Therefore, the correct option is most likely C. where the 2 is supposed to be x.
