your total savings varies inversely with the amount spent on Bill's. if your savings is $300 when your cost of Bill's are $65. W

tatyana61 [14]

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

Lucy’s savings account has 35% more money than her sister Edy’s. Together, the girls have saved a total of $206.80. How much mon

kramer

Let Edy's money be x.

Lucy: 35% more --- (135/100) x

x + (135/100) x = 206.80
(47/20)x = 206.80
47x = 206.8 x 20
47x =4136
x = 88

Edy saved $88.
Lucy saved (135/100)(88) = $118.80
