Answer 1

Part A:
company a: y = 24d + 25
company b: y = 22d + 40
(vairable d = time in days)
(y = cost)

Part B:
Company a:
y = 24 x (4) +25
y = 96 + 25 
y = 121
Company b:
y = 22 x (4) + 40
y = 88 + 40
y = 128
So Company A is the correct answer because it costs $121

Part C:
Company a:
y = 24 x (6) + 25 
y = 144 + 25 
y = 169
Company b:
y = 22 (6) + 40
y = 132 + 40
y = 172

172-169= $3 is saved
