Answer:

-38/7

Step-by-step explanation:

We are given -\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\. First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have \frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}.

The sum of \frac{40}{35}+\frac{112}{35} is \frac{152}{35}.

Now we multiply it by -\frac{5}{4} so we have

\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\

5. A Major League Baseball stadium sells three types of tickets. Reserved tickets are sold for $20 each, field-level tickets are
Ad libitum [116K]

Answer: A) When all three ticket prices generate the same revenue.

Step-by-step explanation:

Reserved tickets cost $20 each.

Field-level tickets cost $50 each.

Seat tickets cost $100 each.

Then if x represents the number of reserved tickets sold, the total revenue for the reserved tickets will be:

R(x) = x*$20

If w represents the number of field-level tickets sold, the total revenue for field-level tickets will be:

F(w) = w*$50

If y represents the number of seat tickets sold, then the total revenue for the seat tickets will be:

S(y) = y*$100

Those equations will intersect when:

R(x) = F(w) = S(y)

This will mean that they will intersect when all three tickets have the same revenue, then the correct option is:

A) When all three ticket prices generate the same revenue.
