A:
If x is number of hours worked and y total pay, in y=9.5x, 9.5 is hourly rate. Isa's hourly rate is 9.5$. From the table: for 2 hours worked Jack earns 16.5$, for 5 hours worked 41.25$ and for 8 66$. Jack's hourly rate is 16.5$/2=8.25$. 9.5/8.25=1.15 Isa earns 9.5$ per hour and Jack earns 8.25$ per hour. Isa's hourly rate of pay is 1.15 Jack's hourly rate of pay.
