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
Answer:
220
This should be correct since you are multiplying by 2
Answer:
- 27
Step-by-step explanation:
Evaluate from the ' inside out ' , that is
Evaluate g(2) then use this value to evaluate f(x) then use this value to evaluate h(x)
g(2) = 4(2)² - 9 = 4(4) - 9 = 16 - 9 = 7, then
f(7) = 7 + 7 = 14 , then
h(14) = - 2(14) + 1 = - 28 + 1 = - 27
