<span>Let x denote number of ounces of 30-cent iodine.
Mixing of 50 ounces of 18-cent iodine and x ounces of 30-cent iodine will result in (50+x) mixture of iodine. We want the mixture to be worth 20 cent per ounce.
The value of 50 ounces of 18-cent iodine is of course
50â‹…18=900.
Similarly, x ounces of 30-cent iodine is worth 30â‹…x.
Finally, 50+x ounces of 20-cent iodine will cost (50+x)â‹…20.
30x+50â‹…18=(50+x)â‹…20
30x+900=1000+20x
10x=100
x=10</span>
Answer:
A = 352 in²
Step-by-step explanation:
A=2(wl+hl+hw) Use this equation to find the surface area of the rectangular prism
A = 2(8x12 + 4x12 + 4x8) Multiply
A = 2(96 + 48 + 32) Add
A = 2(176) Multiply
A = 352 in²
