Answer:
Kristen is correct.
2^3 is the same thing as 2 times 2, times 2. 2 cubed = 8.

Answer:
r= −100c+100d/ct
Step-by-step explanation:
d=c(1+rt/100)
1/100crt+c=d
1/100crt+c+−c=d+−c
1/100crt=−c+d
= 
the answer is $299. If you write an equation, it would be x=35(9)-16. $35 each for 9 lessons. And 2*8= 16.
x=35(9)-16
x=315-16
x=299
