Answer:
$7.46
Explanation:
9.86+5.33=15.19
22.65-15.19=7.46
Wendy = W
Connie = C
Tim = T
Equations
W = C + 4
C = T + 4
W + C + T = 45
Solution
Put W into the third equation
C + 4 + C + T = 45
2C + 4 + T = 45
Put T into the above equation
C = T + 4
T = C - 4
2C + 4 + C - 4 = 45
3C = 45
C = 15
C = T + 4
15 = T + 4
11 = T <<<< Answer
(3,1) is the corect answer
