Answer:
a) The monthly cost for 9 slices is $ 15.75.
b) The monthly cost for [tex]x[/tex] slices is $ 1.75x.
Step-by-step explanation:
a) Total monthly costs due to pizza slices is the number of slices multiplied by the total cost of a slice. If Shaquana bought 9 slices and each slice costs $ 1.75, then the monthly cost for 9 slices is:
[tex]y = (9\,slices)\cdot \left(1.75\,\frac{USD}{slice} \right)[/tex]
[tex]y = 15.75\,USD[/tex]
The monthly cost for 9 slices is $ 15.75.
b) If Shaquana bought [tex]x[/tex] slices and each slice costs $ 1.75, then, the monthly cost for [tex]x[/tex] slices is:
[tex]y = 1.75\cdot x[/tex]
The monthly cost for [tex]x[/tex] slices is $ 1.75x.
