The rec center has two payment choices. Plan A is $35 per month for unlimited visits. Plan B is $15 per month plus $2 per visit.

blsea [12.9K]

Plan B becuase if you multiply 2 by 8 visits you get 16, and then add 15 down for that and you get 31. So 31 is less than 35 and that will be the better deal.

Answer:

Step-by-step explanation:

$i=\sqrt{-1}\to i^2=-1\\\\(5+3i)-(5+3i)(5-5i)\qquad\text{distribute}\\\\=(5+3i)(1-(5-5i))=(5+3i)(1-5-(-5i))=(5+3i)(-4+5i)\\\\\text{use}\ FOIL:\ (a+b)(c+d)=ac+ad+bc+bd\\\\=(5)(-4)+(5)(5i)+(3i)(-4)+(3i)(5i)\\\\=-20+25i-12i+15i^2=-20+13i+15(-1)\\\\=-20+13i-15=-35+13i$
