30% = 0.30
100 - 100(0.30) = 70
20% = 0.20
70 - 70(0.20) = 56
the answer is c

Answer:
10 months
Step-by-step explanation:
Step one
Given
Chuck has $500
Chuckle wants to save $100 monthly
Let the number of months be x
And the total be y
So
Y=500+100x--------1
Holy has $500
Chuckle wants to save $500 monthly
Let the number of months be x
And the total be y
So
Y=1000+50x--------2
Equate 1 and 2
500+100x=1000+50x
1000-500=100x-50x
500=50x
x=500/50
x=10
Two polygons are congruent if they are the same size and shape
The solution is where the lines intersect.
They intersect at the point (0,-1)
x = 0
y = -1
