Answer:
(7*100) can be written as 7*10^2
4 * / 100 i don’t know
if it was 4 * 100 then it’s 4*10^2
if it was divided then it’s 4*10^-2
8* 1/1000 = 8/1000 = 8*10^-3
add together to get 1.100008 * 10^3 (if it was 4*100)
or 7.00048 * 10^2 ( if it was 4/100)

Answer:   The amount of Karen's bill = $ 60 
Step-by-step explanation:
Given : The expression 10+0.25m can be used to determine the amount o, where <em>m =</em> The number of minutes she talks.
If she talks for 200 minutes in one month, then put m= 200 in the above expression we will get the amount of Karen's bill =  10+0.25(200)
= 10+ 50 
= 60
Hence,  the amount of Karen's bill = $ 60
