So for this, you will be dividing 9.3/3.1 and 10^34/10^17 separately.
Starting with 9.3/3.1, that equals 3
Now with 10^34/10^17, remember that the rule with dividing exponents with the same base is that you are just subtracting the exponents. In this case: 10^(34 - 17) = 10^17
Now we put the two quantities together, and your answer will be 3 x 10^17, or the second option.
Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
