Answer
Find out how much money did she start with.
To proof
let us assume that the money she had be x.
As given
woman spent two thirds of her money

Money she had after spent two thirds of her money = Total money - money spent


As given she lost two thirds the remainder


we get

Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder


As given
she had $4 left
thus

x = $36
she start with $36.
Hence proved
Answer:
c = 40 and d = 76
Step-by-step explanation:
this is going to take me a long time to explain but here we go
so you need to do 180 - 116 and get 64.
then create a equation that is like this 7y + 6 + 4y + 64 = 180
when you solve it you get y = 10
then plug in 10 in for y in 4y. and you get 40 for c
do the same for d and you will get 76
pls mark me brainleist because i didnt waster your time.
I believe your answer is D if i am wrong i am deeply sorry.
