After going on a diet, Amy finds that her weight has decreased by 25%.If her weight now is 75kg how much does her weight before?

Her weight before was 100kg.

Step-by-step explanation:

This question can be solved using a rule of three.

Amy finds that her weight has decreased by 25%

So her weight is 100-25 = 75% = 0.75 of the original amount(what it was before).

Her current weight is 75kg.

Her previous weight was x, which is 100% = 1.

So

75 - 0.75

x - 1

Her weight before was 100kg.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
