$4, $8, and $12 because each is a multiple of 4 (4x1=4, 4x2=8, 4x3=12) and they all add up to 24.
2 1/2 pounds = $18
for 1 pound = How many dollars
1 pound = $18 ÷ 2 1 /2
= 18 ÷ 2.5
= $ 7.2
1 pound = 453.6 grams
so 453.6 grams = $7.2
price of 1 gram = 7.2 / 453.6 = $ 0.0158

Answer:
0.00007935
Step-by-step explanation:
7.935 x 10 to negative 5 power can be written as:
7.935 x 10^(-5)
A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

When dividing by tens, move the decimal to the left by the amount of 0's
So our answer is 0.00007935
