Answer:
The piecewise functions accurately represents charges based on Ben's cell phone plan is :

Step-by-step explanation:
Let x be the minutes over cell phone
Let f(x) represents the piecewise function that represents the charges based on Ben's cell phone plan.
We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.
So,
We are also given that For any minutes over 200, Ben is charged $0.35 per minute.
So, Minutes over 200 = x-200

Hence the piecewise functions accurately represents charges based on Ben's cell phone plan is :

60+60×0+1= 61
So your answer is 61.

Answer:
S = 380 - 380*80%
Step-by-step explanation:
Given:
- The original price of the desk: $380
- Discount: 20%
So, the new price of the desk after discounting is:
380(100% - 20%)
= 380*80%
= 304$
The amount of money saved: 380 - 304 = 76$
Hence, the equation can be used to determine the amount of money saved is:
Saving = 380 - 380*80%
Hope it will find you well.
Step-by-step explanation:
you add 9% to a number by multiplying that number by 1.09.
because adding 9% gives us in the end 109% of the original amount.
anyway, the formula for quarterly compounded interest is
Cq = P [ (1+r)^(4*n) – 1 ]
P is the starting principal amount
r is the interest rate per quarter (= interest rate / 4)
n would be the number of years (= 1 in our case).
so, the interest after 1 year is
12500((1 + 0.09/4)⁴ - 1) = 12500(1.0225⁴ - 1) =
= 12500 × 0.093083319 = $1,163.541485 ≈ $1,163.54
If the 3 is supposed to be replaced by any x's, then the answer would be 29 I believe.
