The final cost in dollars to buy robotic kits for the Science Club can be found using
the function c = 49.85n + 7.95, where n is
the number of kits purchased. They want
to purchase at least 8 kits but not more
than 12 kits. What is the domain of the
function for this situation?
F {8, 9, 10, 11, 12}
G {406.75, 456.60, 506.45, 556.30,
606.15)
H 0 < n < 12
0 << 606.15

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

histogram would be best to show the volunteer totals for each clinic and how they differ to each other.
