Question

Please help me with (9, 10, & 12.) If you could find the answer along with the work, that would be lovely. Thanks!

Answer 1

9. Answer: It's a proportional relationship, since every hour he charges $6.25.

Work: there is no work, but you did need the linear equation, which you have written in question 11,

10. Answer: Ratio of how much Steven charges per hour,
$\frac{6.25}{1}$

Work:
$\frac{50 - 31.25}{8 - 5} = \frac{18.75}{3} = \frac{6.25}{1}$
12. Answer: $18.75

Work:
$y = 6.25(x) \\ y = 6.25(3) \\ y = 18.75$
