Question

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c=30.75u+5.75
,where u
is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the range of the function for this situation?(1 point)

0<u≤12

{8,9,10,11,12}

0<c≤374.75

{251.75, 282.50, 313.25, 344.00, 374.75}

Answer 1

Evaluate c = 30.75u + 5.75 for u = 8,9,10,11,12:

u=8 → c = 251.75
u=9 → c = 282.50
u=10 → c = 313.25
u=11 → c = 344.00
u=12 → c = 374.75

So the range is {251.75, 282.50, 313.25, 344.00, 374.75}.
