Question

a company has decreased the weight of its boxes of macaroni by 8 %. if the new weight of the box is 15.1 ​ounces, what was the original weight of the​ box?

Answer 1

8%=0.08 and 100%=1 (100% represents the original weight in percentaje)
If x is the weight you can express: 1x-0.08x=15.1
solve for x: 0.92x=15.1
x= 15.1/0.92=16.1
The original weight was 16.41 ounces

Answer 2

Old weight is equall to 16.413 ounce

Explanation:

New weight = 15.1 ounce

Old weight = x ounce

(Old weight) -8% of old weight= new weight

X - 0.08x= 15.1

X(1-0.08)= 15.1

X*0.92= 15.1

X= 15.1/0.92

X = 16.413

Old weight is equall to 16.413 ounce
