Answer:
x = # of 5 cent coins
y = # of 50 cent coins
x+y=25
.05x+.5y=7.1
y=25-x
(.05x+.5(25-x)=7.1)100
5x+50(25-x)=710
5x+1250-50x=710
-45x=-540
x=12
You have 12, 5 cent coins and 13, 50 cent coins.
The scale for the second values is 56/8 = 7
C = 3 x 7 = 21
C= 21
Day 2
Step-by-step explanation:
Every 20 days, one jar is full.
To find when it was 1/8 full, we multiply the 20 days by 1/8.
20 x 1/8 = 2
C=25m plus 75
