Help pls and thank you

The answer is B.
The answer isn’t A because there are 25 cents in a quarter, not 10 cents.
The answer isn’t C because to pay for something you need to have greater or equal amount of cash.
The answer isn’t D because the letters don’t have a value, as they should be 10d and 25q.
Therefore, the answer is B.

A certain ball is dropped from a height of x feet. It always bounces up to 2/3 x feet. Suppose the ball is dropped from 10 feet
galina1969 [7]

Given that if a ball is dropped from x feet, it bounces up to 2/3 x feet.

And the ball is dropped from 10 feet, that is x=10 feet,

So,before the first bounce it travels 10 feet distance.

Between first and second bounce it travels  \frac{2}{3}* 10 + \frac{2}{3} * 10 = 20*(\frac{2}{3})

Between second and third bounce, it travels 20*(\frac{2}{3})^{2}

Between third and fourth bounce, it travels 20*(\frac{2}{3}) ^{3}

Like that between 29th and 30th bounce, it travels 20*(\frac{2}{3} )^{29}

Hence total distance traveled is

    10+20*(\frac{2}{3} )+20*(\frac{2}{3})^{2} + 20*(\frac{2}{3}) ^{3}+......+20*(\frac{2}{3})^{29}

=10+20[(\frac{2}{3}) +(\frac{2}{3}) ^{2} +(\frac{2}{3}) ^{3} +.....+(\frac{2}{3} )^{29} ]

= 10+20[\frac{\frac{2}{3}*(1-(\frac{2}{3})^{29})  }{1-\frac{2}{3} }]

= 10+20*2*(1-(\frac{2}{3}) ^{29})

= 49.9997 feet ≈ 50 feet approximately.
