Step-by-step explanation:
A= 1000(1+6/100x5)=1300 then 1000-1300=-300
Represent 24 as a sum of two numbers, first number from first die and second number from second die.
24=19+5=18+6=17+7=16+8=14+10=13+11=12+12=11+13=10+14=9+15=8+16=7+17=6+18=5+19=4+20 (the sums 15+9 and 20+4 are absent, because there aren't numbers: 20 on the first die and number 9 on the second die). Totally, you receive 15 different representations of 24.
<span>The probability that the sum of the two numbers facing up will be 24 is

(here

means that you have 20 possibilities to roll first number or blank face on the first die and 20 possibilities to roll number or blank face on the second die).

Just substitute the values: -1/-10-6 -> -1/-16 -> 1/16.

You need to save $30 and each person after 10 saves you $2 so 30/2=15
i think it is 487.5. i may be wrong tho. hope this helps!
