1 gram/ 150 people = 1000 grams / n people
n = 150*1000 = 150,000 people
11 ounces/1.99 = 1 ounce / n
11n = 1.99
n = $.18 per ounce
1 pound = 16 ounces
11/1.99 = 16/ n
11n = 1.99*16
11n = 31.84
n=$2.89
Note: You get $2.88 if you use the rounded answer of $.18 per ounce and multiply that by 16. $2.89 is calculated without rounding the intermediate answer.

If one gram kills 150 people and one kilogram is one thousand grams, than one kilogram of king cobra snake venom would kill 150,000 people.
If an eleven ounce bag costs $1.99 then each ounce cost 18¢ each. Each ounce is 1/16th of a pound. So if eleven ounces cost $1.99 then 16 ounces (or one pound) would cost $2.89.

1)
1000 grams in a kilogram since 1 kg is 10^3 grams.
1000 * 150 = 150,000 people would be killed from 1 kg of venom
2)
a. $1.99 / 11 = $0.1809 per oz
b. $0.1809 * 16 = $2.89 per lb

If 1 gram of venom can kill 150 people then 1 kg =1000g
or 150,000 people 150 x 1000= 150,000
11 oz costs $1.99
.18 per oz.(.181 )
.18 x16= $2.88 per lb.($ 2.89)

1 g / 150 people
1kg = 1000g
So number of people it could kill = 1000g/1g/150 people
= 1000x150 people
= 150000 people
a) cost per ounce = $1.99/11ounce = $0.18/ounce
b) 16 ounces / lb so
cost per pound = $0.18/ounce x 16 ounce/lb
= $2.89 / pound

150x1000=150,000 people.
1.99/11=.18 per ounce.
11/1.99=16/x
11x=16(1.99)
11x=31.84
11x/11=31.84/11
x=$2.90 per pound (rounded to the nearest cent).

1 g / 150 = 1000 / x
solve for x
x = 150,000 ppl
a.) 1.99 / 11 = .180909 = 18.09 cents
b.) 11 / 1.99 = 16 / x
solve for x
x = $2.89
