5/4 is the constant of proportionality
Its c (9) because the opposite of -9 is 9
Hello! I can help you with this! So, you and 3 friends are 4 people. You split $536. To find the amount each of you got, Do division. 536/4 is 134. Each friend got $134 in the first month. You made 224 in 2 months. Let’s subtract to see how much more each of them got. 224 - 134 is 90. Now, multiply by 4 to find out how much profit was made. 90 * 4 is 360. The shop made $360 in the second month.
8:23, after 45 minutes is technically 8: 68
however, the hour ends at 60 minutes, so your true answer is 9:08 pm
hope this helps
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
