A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A
lacrosse goalie saved 7 of 11 shots. How many additional consecutive saves s must the goalie make to
raise his save percentage to 0.850?

Respuesta :

Answer:

The goalie needs to make 16 more saves in a row.

Step-by-step explanation:

Let n be the number of additional saves needed.

[tex]\frac{7+n}{11+n}\geq 0.85[/tex]

[tex]7+n\geq 0.85(11+n)\\[/tex]

[tex]7+n\geq 9.35+0.85n[/tex]

[tex]0.15n\geq 2.35[/tex]

[tex]n\geq 15.66[/tex]
