Answer:
To explain the relation between time and pay and to complete the table.
Given that,
A cashier earns $8 per hour.
Let t be the time in hour worked by the cashier and p be the corresponding pay in dollar of cashier.
we get the relation as,
[tex]t\times8=p[/tex]
Using this formula, we complete the table,
a) Given that, t=4, to find p.
Substitute this in the equation we get,
[tex]p=4\times8[/tex][tex]p=32[/tex]
we get, Pay=$ 32 when time= 4 h
b) Given that, p=40, to find t.
Substitute this in the equation we get,
[tex]t\times8=40[/tex][tex]t=5[/tex]
we get, time= 5 hours, when Pay= $40.
c) Given that, p=40, to find t.
Substitute this in the equation we get,
[tex]t\times8=72[/tex][tex]t=9[/tex]
we get, time= 9 hours, when Pay=$72 .
