Reed is currently r years old. Which expression represents his age seven years from now

Mathematics
1 answer:
lyudmila [28]3 years ago
7 0

Answer: r+7

Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.

Example: Say he is 10 years old now

r = 10

r+7 = 10+7 = 17

meaning he will be 17 seven years from now

6. The revenue function for a production by a theatre group is
Sidana [21]

Answer:

When the ticket price is $3 or $4 the production will be in break even

Step-by-step explanation:

<u><em>The correct question is</em></u>

The revenue function for a production by a theatre group is R(t) = -50t^2 + 300t where t is the ticket price in dollars. The cost function for the production is C(t) = 600-50t. Determine the ticket price that will allow the production to break even

we know that

Break even is when the profit is equal to zero

That means

The cost is equal to the revenue

we have

R(t)=-50t^2+300t

C(x)=600-50t

Equate the cost and the revenue

-50t^2+300t=600-50t

solve for t

-50t^2+300t+50t-600=0

-50t^2+350t-600=0

Solve the quadratic equation by graphing

using a graphing tool

the solution is t=3 and t=4

see the attached figure

therefore

When the ticket price is $3 or $4 the production will be in break even
