Let S and B be savings and bills respectively. Then,
S α 1/B
S = k/B Where k = Constant.
When S = $300, B = 65
Then,
300 = k/65
k = 300*65 = 19500
Therefore,
For B = $145,
S= 19500/145 = $134.48
-1/3
An example that goes through step by step is below:
The Multiplicative Inverse Property. What number can we multiply to 8 to get 1 (the multiplicative identity) as the answer? So, the multiplicative inverse of 8 is 1/8!
Hope that helps!
Hi
7 = 14.70
15= X
so : X = 15*14.70 /7 = 31.5
15 liters of petrol cost 31.5
1/2 + 4x = 5x - 5/6
1/2 = x - 5/6
3/6 = x - 5/6
x = 8/6
