Idk man, im writing this comment because I need points haha
(–c^2)^3*.15c^4
power to a power in exponents is multiply
(–c^2)^3 = (-c^ 6)
= -c^6
-c^6 *.15 c^4
when multiply exponents add the exponents , multiply the coefficients
(-1*.15)c^(6+4)
=-.15 c^(10)
Answer:
its 53
Step-by-step explanation:
We need to construct the system of equations in order to solve that problem. Let's denote one-time membership fee with x and monthly fee with y. Then we can write that John paid x+6y=325 and Abigail paid x+9y=475. Solving the system of equations

, we find that x=25 and y=50. The monthly fee is 50 dollars.
