This can be solved by creating a system of equations.
x + y = 254
12.5x + 10y = 2745
We can then use substitution to solve the system.
x = 254 - y
12.5(254-y) + 10y = 2745
3175 - 12.5y + 10y = 2745
-2.5y = -430
y = 172
Finally, we can use that answer to solve for x.
x + 172 = 254
x = 82
So, there were 82 of the lower box tickets sold and 172 of the upper box tickets sold.

Answer:
3. 9
4. 5 pounds
5. 5/12 of a pound
Step-by-step explanation:
3. "at least 3/8" means to include that column in the count.
4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)
= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that
= 6/8 + 12/8 + 12/8 + 10/8
= 40/8
= 5 pounds.
5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.
40/8 divided by 12 kittens
40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12
40/8 x 1/12
= 40/96
Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to
= 5/12

Answer:
1.8
Step-by-step explanation:
The graph of the problem is plotted using Asymptote and attached.
From the graph:
- 6 Families had 0 Pets
- 3 Families had 1 Pets
- 3 Families had 2 Pets
- 6 Families had 3 Pets
- 1 Family had 4 Pets
- 1 Family had 5 Pets
There are a total of 20 families.
Average Number of Pets
The average number of pets per family is 1.8.
I'm sure it will be <span>57.42 pound</span>
