Answer:
Andrew wins the round.
Step-by-step explanation:
Seeing as red is negative and black is positive, that would make the equations as follows, in the order of Abby, Ashley, Andrew, and Anna.

Meaning that Andrew wins, as his sum is the highest.
Answer:
He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.
A. $8.00 + $1.40 * r
If his parents gave him $26.00, then that is the most Kolby can spend.
$8 + $1.40 * r = $26
Subtracting 8 from both sides:
$1.40 * r = $18
Dividing both sides by 1.40:
r = 12.86
B. Since you can't ride part of a ride, Kolby can only ride 12 rides.
Step-by-step explanation:
To figure out R, add 1.97+0.65 together. 1.97+.065=2.62
0.9 is 0.9278 rounded to the nearest tenth. Hope this helps!
