Answer:
Step-by-step explanation: If 1 minutes of talk = 30 and texting = 30
and each additional minute of talk = 0.50
then the bill would be (for C = total cost)
C = 20+30+(0.45 • x)
OR
C = 50 + 0.45x
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
[ (12 - n)/7 ] = -1
12- n = -7
-n = -19
n = 19
You would divide 76 by 8. That would give you 9.5. Then you multiply by 10 and that gives you 95. Hope this helps (;
