Answer:
let cp be x
mp= x+ (20% 0f x)= 1.2x
sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x
profit = 40
sp-cp =40
1.02x-x=40
x=2000
cp =2000
mp= 1.2*2000=2400
Step-by-step explanation:
In order to solve this problem, we need common denominators. 1/4 multiplied by 3/3 is 3/12. 2/3 multiplied by 4/4 is 8/12. 8/12 + 3/12 = 11/12. We also must add 2 and 16. 2 + 16 is 18. The box weights 18 11/12 pounds.
The answer is 5
