  • a₆ = -5 + 15

Mercedes is going to have her car fixed. Cairo Prince Auto Tech charges $45 for an estimate plus $24 per additional hour of work
strojnjashka [21]
Cairo's cost is modeled by 45 + 24h
Tarantino's is modeled by 30h

For h = 6:
Cairo = 45 + 24*6 = 189
Tarantino = 180

For h = 7
Cairo = 45 + 24*7 = 213
Tarantino = 210

For h = 10
Cairo = 45 + 24*10 = 285
Tarantino = 300

\boxed{2\ and\ 4\ are\ true.}
