If both Cody and Lisa play for t hours, then Cody pays a total of $(7 + t), while Lisa pays a total of $(1 + 3t). If they both pay the same amount P, then
7 + t = P
1 + 3t = P
Solve for t :
7 + t = 1 + 3t
t - 3t = 1 - 7
-2t = -6
t = 3
So Cody and Lisa each bowled for 3 hours, and they both ended up paying P = $10.
53 48 24 should be the answer but im not 100% sure

Answer:
116
2
real
irrational
Step-by-step explanation:
discriminant= b^2-4ac
a=1 b=8 c=-13
discriminant = 8^2 -4*(-13)=64+52=116
if discriminant>0 then we have two real solutions
since √116 is not an integer, solutions are irrational
