OptionB

$10237.5 was paid by Lisa over the last few years.

Step-by-step explanation:

Given that,

Number of donations Lisa has made = 6 donations

Amount Lisa paid first time = $7.50

To find,

Amount Lisa donated to her public radio station over the last few

Solution

7.50 + 4(7.50) + (4*4)(7.50) + (4*4*4)(7.50) + (4*4*4*4)(7.50) + (4*4*4*4*4)(7.50)

= 7.50 + 30 +120 + 480 + 1920 + 7680

= 10237.5

So, the amount Lisa donated to her public radio station = $10237.5
