Answer:
50 pounds
Step-by-step explanation:
we can use the equation 60+80/100x=1(x+50)
we get 80/100 x because the gummy candies are 80 cents or 80/100x
we get 60 from multiplying 1.20$ x 50 = 60
solve:
60+80/100x = x+50
60 = x-80/100x+50
60-50 = 20/100x
10 = 20/100x
x= 10 x 100/20 = 10x5= 50 pounds
Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.
What is a proportion?
A proportion is a fraction of a total amount.
This problem is organized as follows:
- There is a total of 50 + x pounds.
- Of those, 50 cost $1.2 per pound.
- x cost $0.8 per pound.
- The selling price is of $1.
Hence:
[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]
[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]
[tex]50 + x = 60 + 0.8x[/tex]
[tex]0.2x = 10[/tex]
[tex]x = \frac{10}{0.2}[/tex]
[tex]x = 50[/tex]
He should add 50 pounds of gummy candies that cost 80 cents per pound.
