We would find the unit rate. Volunteers per week
So:
6/3 = 2 volunteers per week
4) 41/4, 14/4, 55/6, 34/7,60/8, 47/9, 27/6, 48/5, 31/3, 50/7,
5a) 132/6= 22
b) 146/9= 16.22
c) 147/2= 73.5
d) 107/4= 26.75
e) 156/8 = 19.5
f) 148/9 = 16.44
The slope is 4/3 because rise over run (if u have heard of that expression)
If the amount she saved was $6 for 20%, then the formula for finding savings would be cost*percentage.
But if you want to find the original cost, then you play with the current formula until you get this. $6/20%. Have a good one :)
