Answer:
A. $1852.50
Step-by-step explanation:
Principal amount= P= $3, 900
Rate= r = 19% = 0.19
Time (in years) = t = 2.5
<u>Amount after 2.5 years (A)</u>



Total interest in 2.5 years = A-P = 5752.5 - 3900 = 1852.50
The mean because the data is symmetrical and there are no outliers
Find amount used:
Amount in the card = $20
Amount left = $13.28
Amount used = $20 - $13.28 = $6.72
Find duration of the call:
24 cents = 1 min
672 cents = 1/24 x 672 = 28 mins
Answer: The call was 28 minutes long.
Answer:
Graph g(x) = 2x - 3
Step-by-step explanation:
Plug in (x+1) to f(x) = 2x - 5:
g(x) = 2(x+1) - 5 = 2x + 2 - 5
g(x) = 2x - 3
